Title: TORTURED CORONAE IN THE RAPID BRAKING ZONE

Type: LP Total Time: 565

PI Name: Thomas Ayres

Deep HETGS exposures of four key G0-G5 giants will address fundamental questions concerning their hot magnetized coronae by determining temperatures and densities, probing chemical fractionation processes, and exploring plasma dynamics. The giants lie in or near the "Rapid Braking Zone" where moderate mass stars undergo a radical transformation of their outer atmospheres, perhaps as a relic magnetosphere is disrupted by the onset of a solar-like dynamo. ACIS-I CCD spectra of five G/K supergiants will explore the even more extreme extension of the RBZ to higher masses: where hot coronae mix freely with cool stellar winds. These are ideal targets to exploit the experience gained in the Emission Line Project studies of the active binaries Capella and HR 1099.

Title: COORDINATED CHANDRA/HST OBSERVATIONS OF THE CRAB NEBULA

Type: LP Total Time: 400

PI Name: JEFF HESTER

Recent monitoring of the Crab Nebula with the HST and Chandra sheds new light on both the structure and dynamics of the region into which the wind from the Crab pulsar flows. Bright X-rays predominately originate in regions which contain sharp and highly dynamic structure at visible wavelengths, reflecting the short synchrotron lifetime of the most energetic particles in the nebula. We now have a unique opportunity for an intensive coordinated optical/X-ray campaign to study this dynamic structure. We have an approved and scheduled HST program to monitor the Crab at 11-day intervals during 8 months in the 2000-01 observing season. We request sixteen 25 ks observations with the Chandra ACIS to monitor the X-ray structure and spectrum of Crab during the HST campaign.

Title: THE X-RAY POINT SOURCE POPULATION IN SPIRAL GALAXIES

Type: LP Total Time: 547

PI Name: Andrea Prestwich

Emission from discrete sources dominates the X-ray luminosity in spiral galaxies. We propose to survey a sample of nearby spiral galaxies to characterise the properties of the discrete sources. We have chosen nearby, face-on galaxies which span the Hubble sequence for spirals. Chandra's superb imaging capability will allow us to detect sources down to a luminosity of 4e36 erg s^-1 in the ROSAT band. We aim to classify souces as accretion powered binaries (Low or High Mass) or supernova remnants. Our survey will go more than a factor of 20 deeper than the deepest ROSAT pointings of the same galaxies. This data will enable us to look for trends in the characteristics of discrete sources with Hubble type, metallicity and stellar population.

Title: DETERMINING THE NATURE OF THE VARIABLE ABSORPTION IN NGC 3783 WITH CHANDRA/HST

Type: LP Total Time: 850

PI Name: Ian George

We propose 5 Chandra/HETG observations of NGC 3783, each simultaneous with HST/STIS observations already approved. The observations will allow the accurate determination of the variable continuum, absorption & emission line properties known to exist in this Seyfert, and constitute the most comprehensive study possible of the nature, origin and evolution of the X-ray & UV absorbers in an AGN. Such absorbers constitute a major component of the circumnuclear gas in AGN, and only the HETG has the resolution to make these measurements. It is vital to perform such a detailed study early in the mission to facilitate the correct interpretation of the Chandra & XMM observations of this and other AGN. We also ask the TAC to approve a restructuring of Chandra time already awarded to this study.

Title: FINDING THE BARYONS IN THE LOW REDSHIFT UNIVERSE.

Type: LP Total Time: 500

PI Name: Smita Mathur

Recent estimates of the primordial deuterium abundance, combined with the theory of big bang nucleosynthesis (BBN), imply a baryon density parameter $\Omega_b \approx 0.04 h_{70}^{-2}$. The main reservoir of low redshift baryons is still ``missing''. All the observed stellar and gaseous components add up to only $\Omega_b \approx 0.004h_{70}^{-1}$, a factor of ten below the BBN abundance. Hydrodynamic cosmological simulations predict that a large fraction of the low redshift baryons should reside in a hot diffuse intergalactic medium (IGM). We propose to exploit the excellent spectral resolution of Chandra gratings to probe the low redshift IGM with sensitive X-ray spectroscopy. We expect to detect the main reservoir of low redshift baryons with observations of OVII absorption lines.

Title: A COMPLETE X-RAY CLUSTER SAMPLE AT Z > 0.8

Type: LP Total Time: 365

PI Name: Spencer Stanford

We propose to observe three X-ray selected clusters of galaxies from the RDCS, one at z = 1.1 and two at z ~ 0.8. In conjunction with other data already being obtained by Chandra and XMM, we would then have luminosity and temperature measurements for a complete sample of 8 clusters at z > 0.8. We will produce the first temperature function at these high redshifts. Using Chandra's high angular resolution, we can minimize the contamination from point sources, a serious problem at faint flux limits, as well as study the spatial properties of the intra-cluster medium. With this combination of temperatures, luminosities, and spatial profiles, we will both probe the cluster mass function of the universe at high redshift and study the thermal history of the intra-cluster medium.

We should resolve essentially all of the X-ray background from 0.5-8 keV and will study obscured and high-redshift active galaxies, advection dominated sources, starbursts, X-ray binaries, clusters and groups, and diffuse X-ray emission. The HDF-N field is an ideal one for multiwavelength follow-up studies due to the enormous database already in place.

Title: AN ULTRADEEP SURVEY IN THE CHANDRA DEEP FIELD SOUTH

We propose to exploit the unique combination of angular resolution, sensitivity and field-of-view of the Chandra ACIS imager to perform the deepest X-ray survey ever in the well-studied "Chandra Deep Field South" (CDFS). With a total integration time of 1.5 Msec (request for this AO: 1 Msec) we reach a 0.5-2 keV flux limit of 2E-17 cgs. We aim to detect >500 sources, i.e. AGN to z=10, clusters to z=3 and starburst galaxies to z~1. Simulations based on the existing 130 ksec observation in the CDFS and realistic source counts and correlation function models show, that Chandra exposures will not be background or confusion limited up to 3Msec. We propose to make the Chandra data public immediately.

PI Name: Q. Daniel Wang

We propose an X-ray survey of a 2.4x0.7 square deg field around the Galactic center, using a set of Chandra ACIS pointings. With the unprecedented spatial and spectral resolutions as well as the broad energy coverage, this survey will provide an invaluable database for studying X-ray pulsars, binaries, supernova remnants, and superbubbles as well as many unique features observed in the field. The resultant exquisite X-ray images, complemented by an existing large-scale ROSAT PSPC mapping in soft X-ray, will allow for direct comparison with similar maps in radio and infrared. In particular, the survey will provide an excellent opportunity to determine the origin of the well-known Galactic ridge X-ray emission.

PI Name: Johnathan Grindlay

Our cycle 1 observation of 47Tuc has shown its promise as the ultimate laboratory for study of the production and evolution of compact binaries and compact objects in globular clusters. We propose a deep (4 x 75ksec) ACIS-S observation to measure the complete populations of millisecond pulsars (MSPs) and cataclysmic variables (CVs) by their variability and spectra and to constrain the main sequence binary population. Coordinated HST (ACS) data would provide unique identifications of CVs and many MSPs and allow the full population of quiescent low mass x-ray binaries to be distinguished from CVs. This dataset would provide fundamental constraints for the origins of neutron stars, millisecond pulsars, magnetic white dwarfs and compact binaries in globular clusters.

Title: A CHANDRA SURVEY FOR COMPACT OBJECTS IN SUPERNOVA REMNANTS

It has become increasingly clear that the natal properties of young neutron stars exhibit a rich diversity --- dramatically illustrated by the enigmatic central object in Cas A and hinted at by early 3D modeling of core-collapse. We propose a survey of an objectively constructed sample of nearby SNRs which, when combined with archival data and our vigorous multi-wavelength observation program, will give us a reliable view of the true variety of neutron stars. The ensuing statistics and studies of the central objects will advance our understanding of core-collapse and have bearing on related topics (supernova energetics, natal kicks, etc). We believe that this comprehensive effort, a census of such objects within 5 kpc, will be one of the enduring legacies of the Chandra mission.

Title: MONITORING THE EXTREME X-RAY FLARING OF SAGITTARIUS A* AND A DEEP SURVEY OF THE CENTRAL 40 PC OF THE GALAXY

In Cycle 1, we discovered the first clear evidence of X-ray emission from Sgr A*, the compact radio source associated with the massive black hole (MBH) at the dynamical center of the Milky Way. In Cycle 2, we made the first detection of rapid, large-amplitude X-ray variability of Sgr A*. To gather unprecedented information about the immediate environment of an MBH, we propose a 510-ks ACIS-I observation of Sgr A* to measure the quiescent-state emission spectrum and to characterize the timescales, duty cycle, energetics, and spectral evolution of the flares. Simultaneous monitoring with OVRO and VLBA are being proposed to search for correlated variations and lags predicted by theory to characterize the flaring state emission process. We will also obtain a deep survey in this rich field.

The unique significance of the Antennae for our understanding of mergers and the extraordinary characteristics of the X-ray emission of this system, make this study essential for probing a wide range of fundamental questions on the properties and evolution of XRBs, the range of black hole masses implied by the rich ULX population, the properties of the multiphase ISM, and the evolution of galaxy mergers, that cannot be addressed by looking at more normal galaxies.

We propose to map the ionization and velocity structure of the X-ray and UV absorbers in NGC 5548 with the LETGS and HETGS of Chandra and STIS/HST. NGC 5548 is an important target for this kind of study because 1) it shows multiple kinematic components in the UV characterized by a range in ionization parameter and effective column, 2) it shows evidence for multiple kinematic and ionization components in previous Chandra X-ray spectra, and 3) it has a low Galactic column, which permits coverage of spectral lines out to 80 Angstrom with the LETGS. These data yield the ionization parameter and column density of the absorption-line regions as a function of radial velocity, and constrain the elemental abundances and shape of the unobserved EUV continuum.

Our targets are the high-z counterparts of the best-studied local systems and, combined with 4 others scheduled for observation, form a statistical sample >10 times larger than any previous one in this redshift and luminosity range. Chandra's unique capabilities will allow us to obtain spatially resolved gas temperature and density maps to constrain both the cosmological and physical parameters governing the evolution of the most massive clusters at z<0.5. The proposed observations are complemented by extensive groundbased follow-up studies of weak gravitational lensing, galaxy dynamics and the SZ effect.

PI Name: Michael Corcoran

Understanding the supermassive star Eta Car is important for a variety of topics: the formation and evolution of extremely massive stars and their influence on their environments. Eta Car has been a mystery since its giant eruption in the 1840s. A possible key to the puzzle is the identification of periodic changes in some near IR emission lines, and the discovery of repeatable X-ray eclipses. The next X-ray eclipse will occur during AO4, and we propose to use HETG to observe the variations in the spectral and spatial distribution of the emission during this event. In conjunction with scheduled HST/STIS, INTEGRAL, IR and optical spectroscopy, and radio observations, these HETG observation provide key information which may finally help us solve the riddle of this star.

Science goals include: addressing the mass- and age-dependence of magnetic activity in brown dwarfs; uncovering the low-mass members of the deeply embedded clusters; elucidating the absence of an activity-rotation relation in pre-main sequence stars; measuring flare frequencies, flare plasma conditions and coronal structures in dozens of active stars; investigate the nature of OB wind shocks; and studying X-ray effects on circumstellar environments.

Title: A DETAILED STUDY OF 3C58 - THE YOUNGEST KNOWN PULSAR NEBULA IN THE GALAXY

Type: LP Total Time: 350

PI Name: Patrick Slane

3C58 is the youngest known Crab-like SNR in the Galaxy. Chandra observations have uncovered its young pulsar, provided an upper limit to its surface temperature which challenges standard models of NS cooling, and identified the termination shock of its wind. Structures in the nebula indicative of jets and particle outflows have also been revealed. 3C58 thus possesses all of the standard traits of a young pulsar system, and may be a more appropriate "prototype" than the Crab. Based on the foundation built from our initial studies, we propose a definitive X-ray study of 3C58 to study structure on scales of the telescope resolution, perform spectral mapping of the complex emission regions, and obtain a template for future studies of this remnant of SN 1181 at other wavelengths.

PI Name: John Hughes

We propose deep imaging of the full extents of the young supernova remnants SN1006, Tycho, and G292.0+1.8. These images are optimized for proper motion measurements for which Chandra's superb angular resolution is uniquely suited and will yield significant results when compared to earlier Chandra, ROSAT, and Einstein images. The new X-ray data, in conjunction with our new radio observations, will address questions concerning the physics of ultra-high-Mach-number collisionless shocks, the efficiency of cosmic-ray acceleration, the dynamics of ejecta-dominated SNRs, and the small-scale structure of SN ejecta. These observations will serve as a legacy of the Chandra mission and will provide invaluable data for future research on SNRs and cosmic rays.

Title: SUPERNOVA REMNANTS IN THE MAGELLANIC CLOUDS

Chandra has now observed 20 of the brightest remnants in the Magellanic Clouds. Because the distances are known and the absorption low, this set is going to yield definitive data on remnant characteristics and evolution. We propose to observe 6 more remnants in the LMC. All are fainter and some are larger than those in the observed sample. We expect to see faint central sources and previously unobserved structure. These observations will span a region of parameter space not covered in the presently-observed sample aad will include some remnants with unique interesting features.

Title: FIRST MEASUREMENT OF THE GRAVITATIONAL REDSHIFT AT THE SURFACE OF A NEUTRON STAR

Type: LP Total Time: 680

PI Name: George Pavlov

Chandra observations of 1E1207.4-5209, the neutron star (NS) in the PKS 1209-51/52 SNR, allowed us to discover absorption features in the NS thermal spectrum. This discovery provides a unique opportunity to measure the NS mass and radius and constrain the equation of state. We interpret the features as lines of once-ionized helium formed in the NS atmosphere with a magnetic field of 150 Teragauss, which implies a radius of 9-14 km for a one-solar-mass NS. To measure accurate line energies and resolve potentially multiple lines blended in the low-resolution CCD spectrum, we propose a deep observation with ACIS/LETG. This observation will provide a high-resolution phase-resolved spectrum, required for precise measurement of the NS mass and radius.

We propose a deep X-ray/UV spectroscopy campaign on the bright Seyfert 1 galaxy Mrk 279, using Chandra LETGS, HST/STIS, and FUSE. Our main scientific goal is to study the AGN outflow seen as an ionized absorber in this galaxy, focusing on the crucial connection between the X-ray and UV manifestations of the outflows. We will map the ionization and velocity structure, measure the elemental abundances and then determine the mass and kinetic luminosity flux of the outflow - all stepping stones for studying the importance of outflows in the evolution of AGN and their host galaxies. In addition we will use the LETGS data to determine the existence of relativistic CNO emission lines in the spectrum.

Title: SURVEYING THE FORNAX CLUSTER OF GALAXIES

Low luminosity X-ray clusters of galaxies are the dominant reservoirs of bound matter in the Universe. At a distance of 20 Mpc, the Fornax cluster has an immense collection of the highest quality multi-wavelength data, making it an exceptional laboratory for studying the astrophysics of these systems. We propose surveying an inner region of Fornax with Chandra's unprecedented combination of spatial and spectral resolution to produce a keystone dataset with a long-term legacy. We will investigate the interactions of cluster galaxies with the ICM, their populations of globular clusters, search for emission from dwarf galaxies, ultra-compact systems, and intra-cluster planetary nebulae, and compare the ICM metal contents with the detailed history of stellar populations in Fornax.

Title: CHANDRA OBSERVATIONS OF DLS SHEAR-SELECTED CLUSTERS

The DLS is a deep multicolor (BVRz') imaging survey of 28 square degree being carried out at the 4-m telescopes of the US National Observatories (KPNO and CTIO). The DLS shear-selected cluster sample makes it possible for the first time to study clusters in a baryon-independent way. We are pursuing detailed investigations of this sample with HST and ground-based Keck spectroscopy. Chandra observations will meet multiple high-impact scientific goals, specifically, testing the ``fair sample'' hypothesis, calibrating the relationships between cluster mass, size, X-ray luminosity and temperature, and studying the evolution of these relationships with look-back time.

Title: A CHANDRA WIDE-FIELD SURVEY TO MAP THE COSMIC WEB AND INVESTIGATE THE EVOLUTION OF NUCLEAR ACCRETION

Type: LP Total Time: 515

PI Name: Christine Jones

We propose a wide-field X-ray imaging survey with deep and shallow components in order to map the structure and evolution of the Universe to redshift unity, and to probe the nature, environment and evolutionary history of AGN. The observations will cover the Bootes field of the NOAO Deep Wide-Field Survey, that is unique in its wide-field coverage and availability of deep multiwavelength imaging (including VLA and SIRTF) and optical spectroscopy. The Chandra survey is designed to sample volumes appropriate for statistical investigations of cluster environments, the space density of groups, biases in the optical and X-ray selection of groups and clusters, and AGN phenomena in relation to galaxy host properties and their evolution.

Title: High Resolution Photospheric Spectroscopy of the Neutron Star in EXO0748-676

PI Name: Frits Paerels

Recently, we discovered narrow absorption features in the spectrum of 28 X-ray bursts from the neutron star in the LMXB EXO0748-676, whose properties point to a photospheric origin. The transition wavelengths are consistent with the n=2-3 lines in H- and He-like Fe, exhibiting a gravitational redshift of z=0.35. The measured line strengths indicate that the lines are significantly broadened by the Stark effect, and this will ultimately provide an opportunity to determine both the mass and the radius of this neutron star. Here we propose a very deep spectroscopic observation with Chandra HETGS, to detect the Fe Lyman spectrum and obtain crucial independent spectroscopic confirmation for the Balmer line identification, and to measure the spin period of the neutron star.

Particularly for a detailed study of the various processes that produce and distribute the heavy elements in a core-collapse explosion, Cas A is perhaps the best candidate target. Important results have been obtained with the existing <50 ks observations, but true breakthroughs may be expected with a much deeper exposure that allows us to study nucleosynthesis and core-collapse using Chandra's full spatial resolution.

Inner shell excitation lines from low ionization ions (previously only probed in the UV) will be compared with HST measurements.

A detailed understanding of the mechanisms in the nearby Perseus cluster will unable us to fully understand the solution to the "cooling flow problem". The Perseus cluster is the only extragalactic source with such a high ACIS-S surface brightness over many sq arcmin.

The proposed 500 ks observation, combined with the existing 90 ks, will allow us to determine whether electrons are heated adiabatically or dissipatively in a shock and whether the electron-ion equilibration is efficient. We will search for an electron temperature precursor to the shock to estimate thermal conductivity. We also will determine the importance of gas turbulence and study the destruction of a cooling flow remnant by ram pressure. Combined with data from other wavelengths, this observation can also shed light on the nature of dark matter and the origin of cluster radio halos.

Title: The Extended Chandra Deep Field-South Survey: A Public Chandra Legacy

Type: VLP Total Time: 1980

PI Name: William Brandt

We propose to extend the 1 Ms Chandra Deep Field-South (CDF-S) survey with six public 330 ks flanking observations: the Extended CDF-S (E-CDF-S). Using these, we will study the detailed cosmic history of accretion onto supermassive black holes, the role of moderate-luminosity AGN at high redshift, AGN clustering, and X-ray groups and low-luminosity clusters. The proposed observations are optimized to fill the X-ray luminosity/redshift plane at z > 1.5 where the AGN source statistics are still limited. Follow-up studies will exploit the superb E-CDF-S multiwavelength coverage including VLT/Keck spectroscopy (6000+ VLT redshifts), HST imaging (GEMS, GOODS, ACS Ultradeep Field; 734 HST orbits), intensive ground-based imaging, and scheduled SIRTF observations.

Title: The Balance of Power between Starbursts and AGN: a Chandra/SIRTF Survey.

Type: LP Total Time: 630

PI Name: Belinda Wilkes

We propose a moderate-depth (70 ksec), 0.6 sq.deg. Chandra survey, the deepest/largest CONTIGUOUS area to date, in the Lockman Field of the SIRTF/SWIRE Legacy Survey coincident with a completed, ultra-deep VLA survey with deep optical and near-IR imaging in-hand. SWIRE, the largest SIRTF program, will detect >500 000 dusty galaxies to z > 2.5 in 7 fields covering 65 sq.degs. The prime science goal is to study the structure, evolution and environments of AGN, starbursts and ellipsoids over the SAME SPATIAL VOLUME out to z > 2.5. Key to this study is an X-ray survey deep enough to distinguish starbursts and AGN, including the significant, highly obscured (log Nh>22) subset. Chandra will secure X-ray identification and fluxes for ~550 (0.6 sq deg) of the field's ~7000 SWIRE sources.

PI Name: Carey Lisse

We propose a series of observations of the periodic comet 9P/Tempel 1 in conjunction with NASA's Deep Impact mission. This mission is a spacecraft that will release a 370 kg impactor into the nucleus of the comet on July 4, 2005 at high relative velocity. Our primary objective is to study the generation of prompt x-rays in the impact plume and the change in charge exchange created x-rays as the impact ejecta propgates through the neutral coma. To this end we plan to obtain ACIS-S imaging spectroscopy before, during, and following the impact.

We are requesting HETGS observations of 6 normal O-stars to further explore the characteristics and the origin of the remarkably detailed X-ray line spectra that has been revealed by Chandra. These new targets have been carefully selected on the basis of their normal optical and UV spectra, instead of their X-ray brightness or peculiarity. Along with archival HETGS spectra, this collection will provide complete coverage of the O-star domain in the H-R diagram. The spectra from this unbiased sample will be assembled in a comprehensive X-ray atlas, which will be used to search for morphological trends in the emission lines as a function of stellar parameters. These trends will guide the development of quantitative models to explain the behavior of the X-ray emission lines of O-type stars.

Title: The X-ray Spectrum of a Planetary Nebula at High Resolution

PI Name: Joel Kastner

Planetary nebulae (PNs) provide unique insights into a wide range of astrophysical phenomena. X-ray imaging of PNs by CXO has now broken open the study of very high temperature gas in these objects. To make further progress, we require detailed information concerning gas temperature and composition as a function of position within X-ray emitting PN "hot bubbles." Such information can be obtained only from observations combining high spectral and spatial resolution. We propose a 300 ks LETG/ACIS-S exposure of BD+303639, a particularly X-ray-bright PN. Such a deep, high spectral resolution observation of a PN has yet to be attempted. The proposed observation thus represents a potential breakthrough in our understanding of the origin and evolution of PNs.

Title: The Structure and Composition of Pulsar Winds and their Nebulae

Chandra studies of pulsar wind nebulae have revealed stunning new information on the composition of the winds, the presence of jets and equatorial outflows, and the structure in and around the wind termination shock. Monitoring observations reveal temporal variations in resolved structures that challenge our understanding of particle acceleration and energy flow in these systems. Here we propose deep observations of G54.1+0.3 and PSR B1509-58 in order to probe the complex structure in their interior regions at arcsecond resolution. These observations will allow us to measure the spectrum and morphology of these features in order to constrain models for particle acceleration, the formation and structure of jets, and the geometry of particle flows in PWNe.

Title: Search for Sub-Millisecond Pulsars in 47 Tuc

Type: VLP Total Time: 1000

PI Name: Robert Rutledge

We propose an observation with the ability to detect multiple isolated sub-millisecond pulsars among the unidentified X-ray sources in 47 Tuc, with significant secondary science. Observations in the X-ray band overcome the limited time resolution of even the best radio observations, allowing for the first time the setting of a new ``speed record'' for pulsars at sub-ms periods, below the now 20-year-old record of P = 1.558 ms. The detection of sub-ms pulsars would rule out equations of state for dense matter, provide even better clocks for their many physics applications, and create a strong impetus for future improvement of observational techniques. The absence of sub-ms pulsars would provide compelling evidence for a spin period limit.

Title: Spectra of Neutron Stars with Strongly Magnetized Hydrogen Atmospheres

PI Name: Marten van Kerkwijk

Neutron stars are unique laboratories for matter at extreme densities and magnetic field strengths. Much of the physics is encapsulated in neutron star spectra, but until recently no suitable sources were known. However, over the last year photospheric absorption features - likely due to hydrogen in strongly magnetized atmospheres - have been found for three nearby neutron stars. We propose to obtain high-quality, 300 ks LETG spectra of the two brightest sources. These data will allow examination of the absorption features and permit searches for other associated features. With detailed understandings of these lines one could measure the surface magnetic fields, compositions and temperatures, eventually leading to direct constraints on the equation of state at supra-nuclear densities.

Title: DARK ENERGY WITH X-RAY CLUSTERS: CHANDRA OBSERVATIONS OF 41 HIGH-REDSHIFT CLUSTERS FROM THE 400 deg^2 ROSAT PSPC SURVEY

Type: LP Total Time: 615

PI Name: Alexey Vikhlinin

We propose Chandra observations to measure temperature and gas mass in a sample of 41 high-z galaxy clusters from our 400 deg^2 ROSAT survey. This sample is comparable in number to all clusters in the local Universe (z<0.1) above a similar limiting mass, and covers a factor of 3 larger volume at z=0.4-1. Chandra observations will provide the total mass function estimates at =0.4, 0.5, and 0.65, which can be directly compared with the local measurements at =0.05. These data will provide a measurement of the dark energy equation of state via the cluster evolution test which is completely independent from SN Ia and CMB and has different degeneracies. Some targets in this proposal are in common with the HRC GTO proposal 06900018. These programs are not in conflict.

Our main goals are 1) to observe the turbulence in the intracluster medium by direct imaging of any perturbations of the front surface; 2) to study transport processes in the ICM using the gas density and temperature profiles across the front with a spatial resolution of 1/5 of the Coulomb mean free path; 3) to characterize the magnetic field structure by mapping the onset of the Kelvin-Helmholtz instability.

By determining the energy associated with bubbles and shocks, we can chronicle the mechanical power output of the SMBH. Finally we will study particle acceleration and cooling models by measuring inter-knot spectra along the jet.

Title: Deep Chandra Imaging of the Extended Groth Strip: The Co-evolution of Black Holes and Galaxies

The Extended Groth Strip (EGS) is a half square degree region that has been targeted intensively for galaxy evolution studies. A remarkable array of ultra-deep data have been or will be accumulated, to include radio, near/mid/far IR, optical and UV data of depth comparable to or better than any part of the sky. It is also the subject of the massive DEEP2 redshift survey, giving high quality Keck spectra for 16-17,000 galaxies. The clear gap in the coverage of the EGS is in the X-ray, and we therefore propose to augment the single deep Chandra pointing with 7 more, to image the whole strip. Our goal is to study the co-evolution of galaxies and black holes, by examining in detail the astrophysics of AGN activity, and its relationship to the host galaxy and surrounding large scale structure.

In addition we see the feedback of these massive stars on the interstellar medium in the Perseus Arm: the stellar winds from a massive young cluster (IC 1805) have blown the W4 superbubble and chimney; perhaps an older superbubble is over 100 times brighter in X-rays due to supernovae in its interior (HB3), and the expansion of these bubbles is compressing the W3 molecular cloud and triggering a new generation of stars to form.

Title: The lowest-luminosity quiescent neutron star transient: implications for strong field gravity and the neutron star EoS

Type: LP Total Time: 300

We propose to obtain a 300 ksec ACIS-S observation of the quiescent neutron star (NS) SXT 1H1905+000. Because of a non-detection during a previous 25 ksec Chandra ACIS-S observation, the NS quiescent luminosity is the lowest of all NS SXTs. It also has a low N_H, a well-known source distance, and an accurately known source position. These observations will eliminate the gap in the derived quiescent luminosities between NS and BH SXTs which is used as being evidence for a BH event horizon. Furthermore, this extremely low NS luminosity allows us to derive that 1H1905+000 harbors a cold, massive NS ruling out all equations of state (EoSs) except the stiffest EoSs for NSs with a nucleonic core. Constraining the NS EoS is one of the ultimate goals of NS studies.

In a total of only 300 ksec, we can observe each of the 6 sources in our sample twice, obtaining consistent, robust, and constraining spectra free from photon pile-up. High-res. spectroscopy will break degeneracies in X-ray timing-based models for the accretion flows in these systems, and provide new insights into both the origin of the "kHz" QPOs seen in these sources and the nature of the "Z" and "atoll" tracks they trace in color-color diagrams.

Recent work implies that Kepler's supernova remnant resulted from a Type Ia event, but circumstellar medium (CSM) interaction is also evident.

We propose a 750 ks observation, to map the Fe K alpha line on spatial 5" scales, and obtain high-quality spectra in brighter regions on 8" scales. Fe K will map ejecta and discriminate thermal and nonthermal emission at rims. K lines of other alpha elements will show stratification; all should show Doppler broadening to characterize dynamics. A deep observation of Kepler should be a legacy of Chandra.

We propose to study the overall `ecology' of spiral galaxies - the diffuse ISM and the compact sources within - through a survey of M33, the closest face-on spiral. Our ACIS-I survey will cover the central region of M33 with a sensitivity of 5.E34 erg/s for point sources and 1.E35 erg/s for diffuse ones, at least a factor of two deeper than existing XMM data. More importantly, Chandra's superior spatial resolution will give a detailed view of complex structures (superbubbles, supernova remnants, and truly diffuse hot gas) on all scales > 10 pc, will resolve source confusion that confounds previous studies, and will enable identification of most point sources. The rich data set from the M33 survey, together with what promises to be an iconic image, ought to be part of Chandra's legacy.

Title: A Chandra legacy program: deep study of LMXB populations

Type: VLP Total Time: 1245

PI Name: Giuseppina Fabbiano

LMXBs are the only direct fossil evidence of the formation and evolution of binary stars in elliptical galaxies. To understand LMXB formation and evolution, and address the role of globular clusters (GC) in these processes, we propose a 1,245Ks ACIS-S program to study LMXB populations of elliptical galaxies, to limiting luminosities well in the range of normal neutron star binaries. We will study, and compare with models, the spatial distributions and spectral properties of these sources. We will derive, and compare with population synthesis models, their low-luminosity XLFs. Our monitoring approach will constrain the fraction of transients, thus placing important limits on formation mechanisms, binary evolution and disk outburst theory.

Title: The Cosmological Formation of Galaxy Groups

Type: LP Total Time: 401

PI Name: David Buote

One of the strongest, untested cosmological predictions is the scatter of the concentrations of dark matter halos on the group scale. To quantify this scatter of concentrations requires well-defined samples. We propose a novel systematic study of the core properties of 15 groups representing a complete, X-ray flux-limited sample. In addition to dark matter properties, we will address: (1) entropy and non-gravitational heating, (2) central iron abundances and stellar enrichment, (3) AGN heating and the cooling flow paradox, and (4) the formation of central galaxies. The implications of these measurements for cosmology, supernovae history, star formation and AGN heating will be assessed with numerical simulations. We request observations of 10 unobserved groups in our sample

Title: A Legacy Study of Stellar Life Cycles at the Galactic Center

PI Name: Michael Muno

We propose a set of 27 40 ks Chandra observations of the central 300x80 pc of the Galaxy, as part of a multiwavelength project to study stellar life cycles in the region. Our observations will increase the number of accreting compact objects detected there by a factor of 10, to 12,000. This sample will: (1) increase the known number of HMXBs with IR counterparts several-fold, providing stringent tests of population synthesis models, (2) provide spectral and timing data on a new class of faint X-ray transients, (3) identify the sites of recent star formation by detecting their X-ray luminous WR/O stars, (4) identify elusive young pulsars near the Galactic Center, and (5) constrain the physics of particle acceleration in the mysterious radio filaments.

Title: Accretion or a Corona? Definitive Observations of the Young Accreting Star TW Hydrae

Type: LP Total Time: 500

PI Name: Nancy Brickhouse

We propose a 500 ks observation of the prototypical accreting young star TW Hydrae to determine whether the X-ray emission is from a hot corona or an accretion shock. In the short archival spectrum, O VII and Ne IX forbidden to intercombination lines signal either extremely high densities that must be associated with a shock, or photoexcitation by UV continuum emission. The definitive measurement for the density is the analogous Mg XI line ratio. We will also measure velocity shifts and line broadening, search for rotational modulation, and determine elemental abundances using standard emission measure distribution techniques. This deep spectrum will probe the density and structure of the magnetic regions associated with the accretion process during star formation.

Title: Testing the Physics of Magnetic Accretion: EX Hydrae from the Shock to the White Dwarf Surface

Type: LP Total Time: 500

PI Name: Ronnie Hoogerwerf

We propose to observe the magnetic Cataclysmic Variable (CV) EX Hydrae with the HETG to make a direct measurement of the temperature and density structure of its accretion columns and study the physics of the shock and subsequent cooling flow. The accretion column structure, crucial to our understanding of accretion physics, remains one of the last unexplored components of CVs and other accreting objects. The accretion columns of EX Hydrae are unobscured and are periodically occulted by the body of the white dwarf, making it the ideal target for this study. We will use high signal-to-noise light curves for individual spectral lines to measure the temperature and density structure. The result will be applicable to a broad range of objects from clusters of galaxies to T Tauri stars.

The proposed observations will provide spatial information to interpret the HETG observations and will measure the spectrum at wavelengths > 15 A where the HETG lacks sensitivity. With a projected source > 3 times brighter than it was during our Cycle 5 observation, we will be able to measure for the first time how the temperature distribution and kinematic velocity of the shocked gas has changed and how these parameters vary spatially around the ring-like source. The proposed observation is part of a large multi-wavelength campaign of observations with Spitzer, HST, and ground-based observatories.

For the expansion measurement we will compare to an existing Chandra observation taken in cycle 4 that was specifically optimized for subsequent expansion measurements.

Title: Massive Star Formation and Energy Feedback in the Starburst Region N11

The starburst region N11 is the second largest star formation complex in the LMC. It contains four OB associations distributed in a central superbubble and dense HII regions along its periphery, indicating sequential star formation. Spitzer observations have revealed hundreds of massive protostars in N11. The relatively simple structure of N11 makes it an ideal starburst region for detailed study. We request a 300 ks ACIS-I observation of N11 to determine the X-ray properties of point sources and diffuse emission at arcsecond resolution. This deep observation will allow us to study (1) discrete X-ray source population and empirical L_x/L_bol, (2) X-ray emission from protostars, (3) bubbles/superbubbles and stellar energy feedback, and (4) physical structure of a starburst region.

We also will measure the proper motions and velocity shear of X-ray knots. We will measure the temperature and density structure of the shock around the SW radio lobe to study the hydrodynamics of the lobe/ISM interaction to a level previously seen only in Galactic SNRs. We will detect hundreds of X-ray binaries, probe the GC/LMXB link, and investigate their temporal properties. Finally, we will measure the thermodynamic paramters of the gas and the elemental abundance throughout the ISM.

Title: The Chandra-RBGS Survey of a Complete Sample of Luminous Infrared Galaxies

We propose a Chandra-ACIS survey of a complete sample of Luminous Infrared Galaxies (LIRGs) with Lir >10^11.5, from the IRAS Revised Bright Galaxy Sample (RBGS). All of these objects are interacting/merging gas-rich spirals. Our new observations will provide a uniform and complete census of AGN and X-ray luminous starbursts in the nearest and brightest LIRGs, and will complement approved Spitzer-IRAC+MIPS, and HST-ACS imaging of the same sample. The results will be used to address the following key questions: are binary AGN a common feature of these LIRGs, and if so, when and at what level is the AGN activity triggered in each nucleus ? and can the fueling and growth of massive black holes be correlated in time with the merger phase ?

We propose a 320 ksec HETG observation of NGC 4258. This will yield a high S/N nuclear spectra that is uncontaminated by extended emission or pileup. We will measure the fluorescent Kalpha line strength and width, search for low energy emission lines as expected in some ADAF models, and accurately measure the absorbing column. The latter may be probing the warped disk structure. We will search for nuclear flaring, as observed in Sgr A*. The S/N for observations of the `anomalous arms' will be increased over previous observations. The binary population will be surveyed down to an implied isotropic luminosity of 10^36 erg/s. Our observation will be coordinated with the VLA, to further test the "fundamental plane" of black hole radio/X-ray activity.

Title: The Chandra Deep Proto-cluster Field: Black-Hole Growth and Feedback in Dense Environments

Type: LP Total Time: 400

PI Name: David Alexander

Deep X-ray surveys have revolutionized our understanding of the growth of black holes (SMBH). But these surveys only sample low-density regions at high-z due to their limited solid angle. There is no comparably sensitive X-ray census of AGN in high-density regions at high-z. Such environments evolve into the most massive clusters at z=0, regions which exhibit remarkable trends in galaxy properties - which may reflect early interactions between SMBHs and their host galaxies. A survey of a proto-cluster at high-z would provide a unique view of the interplay of the growth of galaxies and their SMBHs. Here we propose a 400ks survey of the best-studied proto-cluster at high-z, to enable the first definitive study of the growth of SMBHs and their host galaxies in a dense, young, environment.

Title: The Duty Cycle of Supermassive Black Holes: X-raying Virgo

Type: LP Total Time: 453.6

PI Name: Tommaso Treu

Nuclear accretion on to super-massive black holes (SMBHs) plays a key role in the evolution of their host galaxies, as inferred from the ubiquity of SMBHs and the correlations between BH mass, and host mass and velocity dispersion. A fundamental unadressed issue is the actual distribution of accretion rates; we propose snapshot observations of an unbiased sample of 84 early-type galaxies in the Virgo cluster. Together with joint Spitzer 24 um observations, and publicly available HST-ACS and UV data, this survey will probe low-level nuclear activity over four orders of magnitude in black hole mass, thereby delivering the first unbiased census of the duty cycle of local SMBHs.

Title: A Chandra Legacy Survey of Dynamically Active Globular Clusters

Type: LP Total Time: 437.5

PI Name: David Pooley

From our experience with Chandra, we have determined an empirical, successful, and model-independent method for determining the the neutron-star low-mass X-ray binary (LMXB) content and bright cataclysmic variable (CV) of a globular cluster (GC) in a reasonably short ACIS exposure. We propose a program that will discover ~30 LMXBs and ~150 CVs in 31 GCs. When combined with other observations, we will have direct knowledge of over 90% of the total LMXB population in GCs. We will accurately determine the role of GC dynamics in the formation of both LMXBs and CVs. We will also obtain an estimate for the density of the LMXBs and CVs in the field. This study will have important implications both for theories of LMXB and CV formation and for theories of GC dynamics and evolution.

Title: A Deep Chandra Observation of G54.1+0.3

Type: LP Total Time: 300

PI Name: Patrick Slane

Chandra observations of pulsar wind nebulae have revolutionized our understanding of these systems, revealing a wide variety of complex structures that all relate to the basic conversion of spin-down power to an axisymmetric wind with collimated outflows. Based on initial observations, G54.1+0.3 displays Doppler-brightened emission from the wind termination shock region, large-scale jets that form the elongated structure of the nebula, and faint emission that hints at a possible torus as well as large-scale filamentary structure. We propose a Chandra Large Project to obtain deep observations of G54.1+0.3 in order to resolve these structures, study their spectra, and derive properties related to flow conditions and the magnetic field structure of the nebula.

Title: Galaxies across the Octaves: A Chandra Legacy Survey of SINGS Galaxies

Type: LP Total Time: 782.8

PI Name: Leigh Jenkins

We propose to complete a rich, X-ray unbiased, multiwavelength Legacy dataset for a sample of 40 nearby galaxies. These galaxies are a distance limited (d < 10 Mpc) sample from the Spitzer Infrared Nearby Galaxy Survey (SINGS) Legacy program. The sample is now 45% complete. Our observations will detect X-ray binaries as faint as 3e36-1e37 erg/s, allowing us to constrain the X-ray binary/SFR correlation over a large range of galaxy properties and build X-ray binary Luminosity Functions for galaxies across a range of star formation histories. We will produce Legacy datasets and source catalogs for the community, and run theoretical binary population synthesis models in support of this effort.

Title: Probing Dark Energy with Relaxed Galaxy Clusters

Type: LP Total Time: 645

PI Name: Steven Allen

We seek to constrain dark energy using studies of the apparent evolution of the X-ray gas mass fraction in the most X-ray luminous, dynamically relaxed galaxy clusters. The proposed observations will improve the detection of the effects of dark energy from the X-ray data alone to > 5 sigma. More importantly, they will allow us to measure the level of intrinsic (systematic) scatter in distance measurements from this technique and establish whether this is smaller than from type Ia supernovae measurements. Used in combination with supernovae and CMB data, the new Chandra observations will allow the most precise search to date for evolution in the dark energy equation of state - our best approach in trying to understand the origin of cosmic acceleration.

Title: BOW SHOCK, ELECTRON-ION EQUILIBRIUM, BREAKUP OF COOL CORE, AND DARK SUBCLUSTER IN ABELL 520

Type: LP Total Time: 460

PI Name: Maxim Markevitch

Shock fronts provide a unique tool to study the cluster plasma. Only two have been found, those in 1E0657 and A520. Using a long observation of 1E0657, we have determined, for the first time in any astrophysical plasma, that electron-proton equilibration time is shorter than Coulomb - a tantalizing result but based on one object. A520 gives the only chance to confirm it. Its shock also coincides with an edge of the radio halo, enabling tests of the origin of the intracluster relativistic electrons. A520 also exhibits a remnant of a cool core broken up by merger-induced instabilities, providing data on plasma viscosity. Finally, weak lensing map of A520 reveals an intriguing dark subcluster almost devoid of galaxies. We propose a long observation of this exceptionally interesting cluster.

Title: The Great Nebula in Carina: Protoplanetary Disks to Starburst Galaxies

The Great Nebula in Carina is a superb site to study the violent massive star formation and feedback that typifies giant HII regions and starburst galaxies. We propose to map the Carina star-forming complex with a mosaic of 20 new 60-ks ACIS-I pointings as a testbed for understanding recent and ongoing star formation and to probe its regions of bright diffuse X-ray emission. We will provide a catalog of multiwavelength properties of ~12,000 X-ray-selected stars. We will explore superbubble confinement, shocks, cloud evaporation, mass-loading of winds, ISM enrichment, and HII region energetics. We will also examine Carina as a surrogate environment for our Solar System's formation, where protoplanetary disks are bathed in harsh winds and radiation from nearby massive stars.

We propose a very deep (900 ksec) observation of a carefully selected patch of the Galaxy. This observation will provide the most direct and unambiguous answer to the 30-year-old puzzle of the nature of the Galactic "diffuse" X-ray emission. Recent studies comparing the luminosity function of X-ray sources in the Solar neighborhood with the number-flux distributions toward the Galactic Center and plane strongly suggest that the GRXE can be explained by the integrated emission of millions of faint stellar sources - CVs and coronally active stars. The surface density of them is expected to exceed 1 per 60sq.sec in the proposed observation, in sharp contrast to the expectation in the diffuse model. Clearly, Chandra is the only mission in the foreseeable future which can solve this problem.

We propose a deep HETG exposure of the Wolf-Rayet binary system WR 147. The excellent gratings and zero-order data will be used to put tight constraints on the validity of the colliding stellar wind (CSW) mechanism assumed responsible for the X-rays from this object. The detection of broad emission lines with profiles and centroids in agreement with synthetic colliding wind spectra, along with confirmation of the spatially extended X-ray emission reported from the previous short HRC-I exposure, would support the colliding wind picture. On the other hand, narrow (or unresolved) unshifted emission lines would require an interpretation other than CSW. Thus, this study will be the most rigorous test of the CSW paradigm in a WN+OB binary so far.

Title: The cooling neutron star in the super-Eddington accretor XTE J1701-462

Type: LP Total Time: 323

PI Name: Jeroen Homan

Observing the cooling of neutron stars that are reheated by accretion provides new insights into neutron star structure. A detailed and efficient study of this cooling requires the use of Chandra. Here we propose to continue our ongoing monitoring campaign of the neutron star binary XTE J1701-462, a unique system that accreted at super- and near Eddington luminosities for more than 1.5 years before recently returning to quiescence. Our goal is to study the cooling of the surprisingly hot neutron star and also the evolution of the enigmatic non-thermal spectral component in unprecedented detail. Our ongoing strategy of frequent observations (every ~2.5 months) is necessary to test the most recent cooling models. We therefore request five ACIS-S observations for a total of 323 ks.

Title: An Extensive Study of the Youngest Galactic Supernova Remnant G1.9+0.3

We have recently discovered that the smallest Galactic supernova remnant (SNR) in angular size, G1.9+0.3, is the youngest (known) Galactic SNR, with an age of about 100 years. The X-ray spectrum is lineless, well described by synchrotron emission with the highest rolloff frequency ever reported for a SNR. We propose a 500 ks Large Project observation of this unique object, which fills in a gap between SN 1987A (21 yr old) and Cas A (about 330). We wish to study detailed morphology, to compare with the 3 other Galactic synchrotron- dominated SNRs; spectra, to search for spatial variations and thermal emission; and variability, using this study for the first epoch. This object has enormous potential for the study of SNR hydrodynamics and strong-shock physics.

Title: The Spin and Magnetic Moment of the Neutron Star in Cassiopeia A

How do the spin and magnetic moment of a neutron star relate to the properties of its massive progenitor and the supernova explosion? The best opportunity to study this question is the Cas A point source, the youngest known (300 yr) Galactic compact object. Its spectrum is unlike the classical Crab pulsar's, but is instead similar to both the more strongly magnetic "magnetars" and more weakly magnetic young pulsars. Much has been inferred about its progenitor and the supernova explosion from detailed studies of the supernova remnant. We propose to obtain a 500 ks HRC-S observation of the Cas A central point source, combining 350 ks of GO time and 150 ks of GTO time, in order to search for coherent pulsations down to the practical sensitivity limit of any current X-ray mission.

Title: A Deep HETG Probe of the CSM Interaction in SN1996cr

SN1996cr is one of the closest and X-ray brightest SNe detected on the sky. Like SN1987A, it appears to have exploded into a wind-blown bubble, sparking a unique temporal evolution wherein its X-ray flux has increased for >8 years now. Serendipitous HETG data allow us to identify several strong, broad, asymmetric emission-line complexes in SN1996cr, although their low-signal leaves much to interpretation. We propose a deep HETG observation of SN1996cr to resolve these emission lines and elucidate their nature (velocity structure, line diagnostics, abundances). It is imperative to observe SN1996cr while it remains bright, as it is the only SN beside SN1987A where such an observation is practical and in many ways is more representative of CSM-interacting core-collapse SNe.

The region of highest resolution (FWHM < 1.5") will cover the same field of view as recent deep HST and Spitzer observations. It will be the most data-rich X-ray study of a starburst galaxy ever (>1E6 counts), and will greatly advance our knowledge of the soft X-ray-emitting gas in the superwind, the very hot metal-enriched plasma within the starburst region, and the the X-ray point source population in both the starburst region and the galactic disk. It will further complement the investment made in observing M82 by the other Great Observatories, Hubble and Spitzer.

Only Chandra can resolve the multiple components of these sources, as is needed for an improved understanding of source physics and gas heating. The imaging and spectroscopy of cores, jets, hot spots, and atmospheres will be of permanent legacy value. We will use the data to investigate particle acceleration, interactions between radio plasma and the ISM and IGM, the emission mechanisms of hot spots, and AGN fueling. Comparison with our complete Spitzer coverage and HST images will aid interpretation. The dataset will be made public immediately.

We aim to detect and measure the ionization state and outflow velocities in the well-studied low-BH-mass AGN NGC 4051. We have been granted a 340 ks Suzaku observation to study continuum and low-resolution line spectral variability; HETG spectroscopy complements this by isolating narrow absorption lines arising from key zones of gas, allowing us to measure ionization, column and outflow velocities of the multiple ionized zones. A moderately ionized zone in particular can mimic the appearance of a broad Fe emission line but can be revealed by 6.5 keV Fe Kalpha absorption, for which there is already tentative evidence. A 320 ks HETG exposure will provide powerful diagnostic signatures across a wide range of ionisation. We also request HST time for tie-in UV spectroscopy.

Powerful AGN outbursts in galaxy clusters can release upward of 1E61 erg into the intracluster medium. Events of this magnitude are able to quench cooling flows and drive large-scale outflows that redistribute and heat the gas on cluster-wide scales. The most potent example of this is seen in the z=0.22 cluster MS0735.6+7421, whose powerful shock and cavity system have injected an estimated 6E61 erg of energy into the ICM. We propose to obtain a 500 ksec ACIS image of the cluster to examine in detail the relationships between the shock, cavity, and radio systems, and to investigate the impact of powerful AGN outbursts on the structure of the cluster.

Title: The Role of AGN in Massive Galaxy Formation

Type: LP Total Time: 309

PI Name: Spencer Stanford

There is increasing evidence that high rates of star formation in massive galaxies was common in rich environments at z > 1. The leading candidate for quenching the star formation and transforming cluster galaxies into red sequence galaxies is AGN. Therefore we expect to see an increase in AGN incidence in dense environments at z > 1. We propose to systematically determine the incidence of AGN in galaxy clusters at 1 < z < 1.5 using moderately deep ACIS imaging of IR-selected clusters in the Bootes field. In conjunction with extensive data from Spitzer, HST, and Keck, we will test the AGN quenching paradigm for the origin of the stars in massive galaxies.

Title: Shocks, Ripples, and Bubbles: A Very Deep Observation of Abell 2052

The cooling flow cluster A2052 has, arguably, the morphology most similar to the Perseus cluster as seen with Chandra. Two clear bubbles to the N and S of the center of A2052 are filled with the radio lobes associated with 3C 317. Surface brightness discontinuities consistent with shocks with Mach numbers of 1.8 and 1.2 are seen near the cluster center. These may be isothermal shocks. We propose to observe Abell 2052 much more deeply to study these shock features, ripple features due to sound waves that may be found at larger radii, possible ghost bubbles, cooling gas in the bright shells around the radio source that may link the X-ray and H-alpha emission, and possible hot gas within the X-ray holes. We will directly compare the star formation and cooling rates in the cluster center.

Title: A Benchmark Observation of the Warm-Hot Intergalactic Medium

Type: LP Total Time: 500

PI Name: Taotao Fang

Searching for the ``Missing baryons'', in the form of the warm-hot intergalactic medium (WHIM), is a fundamental challenge faced by the current theory of structure formation. Cosmological simulations predict that majority of the WHIM can be probed in X-ray only, yet the reported detections are often in question due to statistical and systematical issues. Based on the tentative evidence in our joint XMM-Chandra ToO observations of H 2356-309, we propose a deep, non-ToO Chandra observation to definitively detect the WHIM absorption line with a measured column density expected from theory. A null detection would place an upper limit which cannot be explained by current cosmological simulations, and put future pursuit of the WHIM with current generation of X-ray telescopes in question.

Title: Cosmic archaeology with Chandra: from a supergiant shell to young stellar objects in NGC 602

Type: LP Total Time: 300

PI Name: Lidia Oskinova

The Wing of the SMC has low metalicity, and low content of gas and dust. It provides an ideal nearby laboratory to study star formation and feedback in an environment that resembles the early Universe. We propose a 300 ks Chandra observation of NGC602, a massive star cluster at the edge of a supergiant shell in the Wing. This cluster has a simple morphology and is located in a region of high transparency for X-rays. The Chandra data will help to answer the fundamental questions about the mechanisms that sculpture the largest structures in the ISM, and trigger the formation of stars. This observation will be complemented with data from other NASA Great Observatories HST and Spitzer, and will establish a template for studies of active star formation in external galaxies.

Title: New Thrust for Jets: Understanding the Physics of Young Stellar Jets and Outflows

Type: LP Total Time: 360

PI Name: Manuel Guedel

We propose a deep ACIS observation of the jet system of the classical T Tauri star DG Tau. DG Tau is so far unique because both its jet and counter-jet have been detected in X-rays. We will study jet structure, temperatures and proper motions of the sources and model the heating, propagation, and cooling physics of the hot plasma jets. The system orientation allows the counter-jet to be viewed through the circumstellar disk. X-ray absorption by the disk gas can thus be reliably determined and be used, together with optical information, to determine the gas-to-dust ratio in the disk. We will request radio (VLA) observations for complementary imaging, and near-IR (VLT) observing time for high-resolution spectroscopy to characterize the jet shocks and measure extinction along the jets.

Title: The Chandra Cygnus OB2 Survey

Type: VLP Total Time: 1080

PI Name: Jeremy Drake

Understanding massive "starburst" clusters is crucial for the first stars, starburst galaxies, galactic and ISM evolution, and star and planet formation on universal and galactic scales. But Galactic superclusters are generally too distant for detailed study. Recent awareness that Cygnus OB2 (1.5kpc; ~2Myr old) has supercluster characteristics has sparked a multiwavelength legacy effort exploiting its proximity to study starburst astrophysics. This Chandra Legacy project will provide an exquisite vision of the anatomy of a massive "collapse" mode of star formation, allowing detailed archeology of its history and content. 8000-10000 detections down to 0.1Msun will incisively test theories of giant molecular cloud collapse, massive star formation and protoplanetary disk evolution.

Title: A Detailed Study of the Aged O-Rich Supernova Remnant 0049-73.6

Type: LP Total Time: 450

PI Name: Sangwook Park

O-rich supernova remnants (SNRs) provide an excellent opportunity for the study of core-collapse (CC) nucleosynthesis and the late-stage evolution of a massive star. While young O-rich SNRs (e.g., Cas A and G292.0+1.8) are being extensively studied, such studies are intrinsically limited because the early-stage of the blast wave and reverse shock may not reveal the full nature of metal-rich ejecta and the surroundings. Studies of relatively old O-rich SNRs are essential for a comprehensive understanding of CC SNRs, complementing those of young SNRs. The old O-rich SNR 0049-73.6 is a perfect example for such a study, revealing both high- and low-Z ejecta and well-evolved blast wave. Thus, we propose a deep 450 ks ACIS observation of 0049-73.6 for a detailed X-ray imaging spectroscopy.

Title: A Detailed Study of the Type Ia Supernova Remnant G299.2-2.9

PI Name: Sangwook Park

Supernova remnant (SNR) G299.2-2.9 is a unique example of the Type Ia SNR which allows us a detailed 2-D spectral study for both of the metal-rich ejecta and ambient structures. Such studies of the ejecta and ambient medium are essential to reveal the detailed SNe Ia explosion mechanisms and their specific environments, which would critically impact their utility in cosmology. The proposed studies of both of the Type Ia SN ejecta and ambient structures cannot be performed with young historical Type Ia SNRs, and the mid-aged Type Ia SNR G299.2-2.9 provides a unique opportunity. Thus, we propose a 640 ks Chandra observation of G299.2-2.9. The proposed observation will serve a legacy which will be an essential basis for a high resolution spectroscopy of Type Ia SNRs with IXO and Astro-H.

Title: Ultra-Luminous x-Ray Sources in the Most Metal-Poor Galaxies

Type: LP Total Time: 286.44

PI Name: Andrea Prestwich

There is growing observational and theoretical evidence to suggest that Ultra-Luminous X-ray sources (ULX) form preferentially in low metallicity environments. Here we propose a survey of 27 nearby (< 30Mpc) star-forming Extremely Metal Poor Galaxies (Z<5% solar). There are almost no X-ray observations of such low abundance galaxies (3 in the Chandra archive). These are the most metal-deficient galaxies known, and a logical place to find ULX if they favor metal-poor systems. We plan to test recent population synthesis models which predict that ULX should be very numerous in metal-poor galaxies. We will also test the hypothesis that ULX form in massive young star clusters, and ask for HST time to obtain the necessay imaging data.

Title: Accretion onto nuclear black holes in early type galaxies: comparing field vs. clusters

Type: LP Total Time: 564.2

PI Name: Elena Gallo

IF black holes are indeed ubiquitous in galactic nuclei, little is known about the frequency and intensity of their activity, the more so at the low-mass/low-luminosity end. Our cycle 8 observations of the Virgo clusters have delivered the most comprehensive measurement of the duty cycle, showing that although black holes are present even in low mass spheroids, activity is a strong function of mass. However, nuclear activity is also expected to be a strong function of environment, which regulates the gas supply through processes such as ram pressure stripping and merging. We propose the first systematic study of the effects of the environment on low level accretion, by combining our Virgo study with new observations and archival data of a volume limited sample of 100 field spheroids.

Title: The Size of Quasar Non-Thermal/X-ray Emission Regions

Type: LP Total Time: 584

PI Name: Christopher Kochanek

We will use microlensing, where the stars in a lens galaxy magnify the accretion disk of a gravitationally lensed quasar, to measure the sizes of the X-ray emission regions of 7 gravitationally lensed quasars with well-sampled optical light curves and accretion disk size measurements. We will use these to determine the scaling of the non-thermal emission regions with black hole mass. For two ``active'' systems, RXJ1131-1231 and Q2237+0305, we will use longer observations in order to measure the X-ray energy dependence of the size. We have HST time to monitor the 6 with UV flux to probe thermal emission from near the inner edge of the disk. These observations can only be done with Chandra because future X-ray observatories will lack the necessary angular resolution.

Title: The environmental and epoch dependence of radio-loud AGN feedback

Type: LP Total Time: 400

PI Name: Judith Croston

Feedback from radio-loud AGN outbursts is now thought to be an important ingredient in galaxy formation models, potentially solving the `cooling flow' problem in cluster centres and helping to resolve long-standing problems in reconciling CDM models with observed properties of groups and clusters. Now that the role of radio-loud AGN feedback is established, the next step is to understand the relationship between radio-loud AGN energy input, environment and epoch, which appears complex and is currently poorly understood. This Chandra Large Project aims to address this question by characterizing the environments of a unique sample of radio galaxies spanning three orders of magnitude in radio luminosity at a single, cosmologically interesting redshift.

Title: Jet-ISM Interactions in a Restarting Radio Galaxy 4C 29.30

Type: LP Total Time: 300

PI Name: Aneta Siemiginowska

We propose to study interactions between radio plasma and ISM with a deep 300ksec Chandra ACIS-S observation of a low redshift radio galaxy, 4C 29.30 where the complexity of such interactions is uniquely displayed allowing a direct mapping of the initial stage of the radio source growth. The high resolution Chandra image will match the resolution of optical and radio structures observed in this source. The X-ray morphology will provide the critical information needed for studying physical conditions and understanding the impact of the evolving radio source onto the host galaxy environment. Our target presents a great laboratory to study the physical mechanisms of AGN feedback, and so provide strong constraints on models of galaxy evolution.

Title: Extending the Deep Image of the Perseus Cluster: The Outer Bubbles, Filaments and Ripples

Type: LP Total Time: 700

PI Name: Andrew Fabian

Our existing 900ks image of the core of the Perseus cluster has revealed a wealth of detail on the bubbles, shocks and ripples caused by the action of the central AGN on the surrounding ICM. Most of the advances are directly due to the high surface brightness of the Perseus cluster (higher than any other cluster) and to the high spatial resolution of Chandra. This resolution is degraded significantly 4 arcmin or more off-axis, meaning that the region studied at the highest resolution is quite small. Here we propose three further exposures totalling 700ks to extend the highest resolution region, covering areas to the N and S of the nucleus where the current data suggest the presence of further intriguing and important structures due to the AGN activity.

Title: Chandra Observations of a Complete Sample of SZE Selected Galaxy Clusters

Type: LP Total Time: 346.3

PI Name: Joseph Mohr

We propose to obtain X-ray observations of a complete sample of 16 SZE selected galaxy clusters from the South Pole Telescope (SPT) survey. The SZE selection produces an approximately mass limited sample (at all redshifts) over the existing 200 deg^2 SPT survey. The Chandra observations provide X-ray mass estimates and morphologies, allowing (1) an initial calibration of the SZE flux-mass relation and (2) early tests of cosmology and the evolution of structure. Our 346ks request leverages 625ks of GTO time in AO10/11; these X-ray data are crucial to developing an understanding of the new window on the universe that SPT has opened and in laying the foundation for future studies using the full SPT survey (~1400deg^2 by 2010).

Title: COMBH: Chandra Observations of M-sigma Black Holes

Type: LP Total Time: 510

PI Name: Kayhan Gultekin

Galaxies with dynamically-measured central BH masses allow us to understand BH accretion, jets, and interactions between BHs and host galaxies with a clarity not possible in random surveys. By measuring true Eddington fractions, we can calculate the energy in radiation vs mechanical jet energy and the efficacy of BHs in heating nuclear regions and affecting star formation. Remarkably, 1/3 of SMBHs making up the M-sigma relation have been poorly observed or totally unobserved with Chandra. We propose a survey of 15 M-sigma galaxies to complete the sample of reliable M-sigma SMBHs. For each galaxy we propose to obtain 30-60 ks exposures and an hour-long VLA observation. This survey will test and extend the fundamental plane of BH activity and facilitate studies of the origin of M-sigma.

Title: A Long Look at NGC 3603, the Milky Way's Starburst Cluster

PI Name: Leisa Townsley

NGC 3603 is one of the youngest truly massive stellar clusters in the Galaxy and serves as a springboard for understanding super star clusters such as R136 in 30 Doradus. Recent advances in infrared imaging and UV/visual spectroscopy applied to NGC 3603 are yielding new catalogs of pre-Main Sequence stars and new spectral types for massive stars; advances in ACIS analysis techniques now give robust X-ray source properties in crowded fields that facilitate comparison with these new datasets. We will apply these new methods to a deep ACIS-I observation of NGC 3603 to study its massive stars (3 W-R + >100 O stars, including over half of the Galaxy's O3 stars), thousands of pre-main sequence stars, and diffuse X-ray emission that pervades the cluster, perhaps indicating cavity supernovae.

FK Com (GIII) is an ultra-fast rotator - a coalesced binary that has spun up - and provides unique insights into activity at the extremes of dynamo action. Two consecutive Chandra orbits of ACIS-S/HETG and 20 orbits of HST/COS observations will be combined with contemporaneous Doppler imaging maps and spectropolarimetric field measurements to build 3D coronal models. We will: locate dominant coronal and TR structures using Doppler shifts; measure emission scale heights via rotational broadening; derive densities, abundances, and EM in both quiescent and flaring plasma; constrain the dynamic processes by line profile modeling; and measure microflaring effects. Results of this LP will provide a detailed legacy view of the workings of coronae at their extreme edge.

Title: X-rays from Planetary Nebulae: Unveiling Binarity, Magnetic Fields, and Wind Collisions

Type: LP Total Time: 930

PI Name: Joel Kastner

Chandra has yielded unparalleled insight into the processes involved in shaping planetary nebulae (PNe), via the detection of diffuse and/or point-like X-ray sources within PNe. Diffuse X-ray sources, whether due to ``hot bubbles'' or to collimated outflows or jets, allow us to probe the energetic shocks within PN wind interaction regions. Meanwhile, X-ray point sources in PNe provide unique diagnostics of circumstellar magnetic fields, accretion disks, wind shocks, and/or binary companions at PN cores. These results from Chandra's first decade have prompted the community of PN astronomers to propose the first systematic X-ray survey of PNe in the solar neighborhood.

Title: X-RAY IMAGING OF NOVA SHELLS

Type: LP Total Time: 650

PI Name: JENNIFER SOKOLOSKI

Novae are the most common stellar explosions in the Universe, and the most energetic after GRBs and supernovae. Like other stellar explosions, optical data show that novae are aspherical and inhomogeneous. Although novae are known to be triggered by a thermonuclear runaway (TNR) on an accreting white dwarf, the means by which the observed structure is produced is less clear. Since the shaping of nova remnants must produce shocks, and thus X-rays, Chandra imaging provides a powerful tool for understanding how novae produce their rings, clumps, and jets. We propose a major comparative study of the X-rays from nova shells to determine the processes that shape the ejecta. This work has wider implications for the physics of jets and asymmetry production in all types of stellar explosions.

Despite having only moderate hard X-ray sensitivity, the INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL) has greatly expanded our knowledge of High-Mass X-ray Binaries (HMXBs) by finding large numbers and new types of HMXBs. There are good reasons to think that even fainter HMXBs should be present, and we propose to use Chandra to survey part of the Norma region, which is the location with the highest density of HMXBs. This will be important for understanding the HMXB population and its evolution, the HMXB luminosity function and how faint wind-accrting HMXBs can be, as well as providing critical estimates for Advanced-LIGO source rates. IR follow-up is proposed, and the subarcsecond Chandra positions are critical.

Title: A Survey of PWNe around Narrow-Pulse Gamma-ray Pulsars

We propose here, on behalf of the Fermi LAT team, ACIS observations of the X-ray counterparts of six unusual gamma-ray pulsars discovered by the LAT. The targets, four seen only in the gamma-rays, two also radio-detected, have unusual single or narrow double pulse profiles, which require particular emission geometries for different pulsar models. By measuring the arcsecond-scale structure of the wind nebula termination shocks of these young (<100kyr) objects, CXO can pin down the viewing angle and test the pulsar physics. All have known X-ray fluxes and we can also extract spectral and distance estimates needed to interpret the GeV gamma-rays. The survey sample covers a range of ages, spindown powers and expected inclinations, making it a powerful test of pulsar emission models.

Type: VLP Total Time: 1000

PI Name: Kazimierz Borkowski

X-rays in G1.9+0.3 are produced primarily by energetic electrons accelerated in its very fast blast wave. However, the radio-bright but X-ray faint northern shell shows prominent thermal emission from supernova ejecta. Doppler broadening velocities are of order 26,000 km/s. An additional spectral line at 4.1 keV is emitted by radioactive 44Sc produced by the electron-capture decay of 44Ti. The line flux implies an initial mass of 44Ti synthesized in the explosion of 1.9 x 10-5 solar masses. The spatial distribution of 44Sc hints at an asymmetric explosion. We propose a 1 Ms Chandra observation, with the primary goal of mapping 44Sc emission. This observation will establish the degree of asymmetry of the explosion, and may distinguish between core-collapse and Type Ia origin for G1.9+0.3.

Here we propose a deep ACIS-S observation of M83. In addition to detailed spectral and temporal studies of the brightest 50 sources, we will relate the X-ray properties of the SNRs, XRBs, and diffuse X-ray emission to the local environment, using the underlying stellar population and/or distance from features like the spiral arms to constrain the progenitors of the sources, to test population models, and to explore the physical mechanisms responsible for diffuse emission.

By performing a detailed modeling of the emission-line spectra, we will determine (1) the spatial extent of the outflow, (2) its velocity structure, and (3) the mass and energy rates imparted by the outflow into its environment. Our results will provide the first X-ray test of whether outflows in such early-type galaxies expel, as expected, significant quantities of material during their hosts' transition from the blue cloud to the red sequence.

Markevitch et al. 2002). We propose a deep observation of Abell 2146 to test electron-ion equilibrium, which was found to be shorter than the Coulomb time in the Bullet cluster, and investigate the ICM transport processes by studying the complex substructures and shocks in the subcluster tail.

Title: Chandra Observations of the ACT Sample of SZE-Selected Galaxy Clusters

PI Name: John Hughes

We propose to obtain Chandra observations of a complete sample of galaxy clusters detected by the Atacama Cosmology Telescope (ACT) using the Sunyaev-Zeldovich effect (SZE). The proposed ACIS-I observations of 14 massive, newly-discovered SZE clusters will provide a precision calibration of the SZE signal versus mass correlation out to redshifts of 1. This effort is part of an intensive multi-wavelength campaign to produce an unbiased, well-observed sample of massive galaxy clusters out to high redshifts for cosmological investigations. These proposed observations will allow us to link directly the X-ray and SZE properties of massive clusters, so that cosmologists can reliably utilize the new large cluster samples that are being accumulated from both Chandra and the new SZ experiments.

Title: Securing a Detection of the Bulk of the Missing Baryons

Type: LP Total Time: 500

PI Name: Fabrizio Nicastro

We propose to optimize the use of X-ray and FUV observatories to settle unambiguously one of the most controversial and open problems of modern astrophysics: the existence of the Missing Baryons in a Warm-Hot Intergalactic Medium (WHIM). We will do this by targeting a 500 ks Chandra-LETG observation on the best available tracers of the bulk (~80%) of the Missing Baryons in the Universe: two intergalactic absorption systems recently detected through Broad HI Lya and triple-OVI absorption, respectively, in a moderate S/N HST-COS spectrum of the bright and relatively high-redshift (z>0.4) blazar 1ES 1553+113. The proposed observation is carefully designed to finally secure a detection of the WHIM and to obtain a first robust estimate of its metal content.

We propose the `ultimate' resolution Chandra imaging survey (CHEERS) of a far-IR selected sample of active galactic nuclei (AGN) from Schmitt et al. (2003). With complementary high resolution HST and radio data, CHEERS will (1) resolve the detailed X-ray morphology of the extended narrow line region and obtain full picture of the multiphase interstellar medium (ISM) with typical resolution of 0.4 arcsec; (2) investigate the X-ray emission mechanisms at AGN jet-ISM interaction regions and (3) measure mass and momentum outflow rates to evaluate the importance of AGN feedback. To achieve these goals, we request 335 ks ACIS-S observations and 5 HST orbits to supplement the archival data.

Title: Detecting the Hot Wind Escaping from the Galactic Center of the Milky Way

Type: LP Total Time: 300

PI Name: John Stocke

We propose a 300 ksec ACIS + LETG exposure to detect and study our own Galaxy's outflowing nuclear wind. We have used HST and FUSE to discover the absorption signature of this wind in intermediate (e.g. C III) and high (e.g. O VI) ions towards two extragalactic targets above and below the Galactic Center. One of these targets (PKS 2005-489) is bright enough to observe at low resolution with Chandra to address two important questions about this wind: (1) Does any portion of this wind (e.g., O VII & O VIII ions) escape the Galaxy? The C III & O VI ions do not have escape speed; and (2) What is the ionization state and thus the metallicity of the gas? The mass flux, dynamics, and metallicity of this wind will give us valuable insight into the star formation history of the Milky Way.

The program, also involving a series of ground observations, will be a unique experiment: using three space telescopes we will, for the first time, monitor hundreds of young stellar objects simultaneously over a broad wavelength range.

In combination with 74 ks archival data, we will make very high signal-to-noise measurements of emission line profile shapes, which sensitively measure the wind optical depth as a function of wavelength. We will use the wavelength dependence of wind optical depth from all usable lines to make a precise measurement of the mass-loss rate. The wavelength dependence of wind optical depth will also test the importance of porosity. We will use XCMFGEN, our powerful new radiative transfer code, to construct global models which will be fit to X-ray, UV, and optical data, providing the strongest possible constraints on stellar and wind properties.

Title: Deep Imaging of M37, A Better Hyades

Recent studies suggest that the picture of stellar LX decaying from 10 Myr to 5 Gyr as a single power-law is overly simplistic. M37, a Hyades analog, has been carefully surveyed in the optical, and we propose complementary deep (450 ksec) ACIS-I imaging of this open cluster. M37's rich membership, good match to Chandra's FOV, and large number of measured periods (~700) make it ideal for examining the evolution of coronal X-ray emission. Together, our X-ray and optical data will provide independent determinations of LX and v_rot; map out M37's X-ray luminosity function, with stacking of optically similar sources extending our flux limits by ~10x; test whether magnetic effects produce anomalous optical colors/luminosities for high LX sources; and characterize M37's interacting binaries.

Remnant of the brightest SN in recorded history, SN1006 is the object where the connection between SNR shocks and cosmic rays was first confirmed observationally. It is the closest and least absorbed of all the historical SNRs--yet it has been the least observed by Chandra. We propose deep ACIS observations to: 1) measure proper motions (through comparison with earlier data) to give the shock velocity around most of the shell; 2) elucidate the physics of nonthermal shocks and diffusive acceleration in unprecedented detail; and 3) study small-scale ejecta knots within SN1006 to obtain abundances and constrain the explosion properties. The new data will complete deep coverage for the entire SN1006 remnant, so deep studies of all the historical SNIa remnants will at last be in the archive.

Title: Bowing to Pressure During the Reformation: A Study of the Composite SNR G327.1-1.1

PI Name: Patrick Slane

G327.1-1.1 is a composite supernova remnant whose pulsar wind nebula is defined by an offset radio nebula and a cometary X-ray nebula surrounding a neutron star that appears to be moving rapidly through the remnant. Complex structures indicate that the PWN has been disrupted by the reverse shock of the SNR, and that the nebula is re-forming while being swept back into a bowshock-like morphology by the pressure associated with its rapid motion. The manner in which a PWN evolves through such a stage determines the ultimate spectrum of its relativistic particles, and the process by which they eventually escape into the ISM. We propose a deep Chandra observation of G327.1-1.1 in order to study its complex spectral and spatial structure during this crucial phase of evolution.

Title: M51: Using the Kinematics of a Grand-Design Spiral to Understand the Physics of the Hot ISM, SNRs, and XRBs

PI Name: K.D. Kuntz

M51 is an iconic grand design spiral galaxy with a strong arm/inter-arm density contrast and a high star-formation rate, but with very little star-formation between its arms. As a result, one can age-date the hot gas and high-mass binaries produced in the arms that have moved into the inter-arm regions. We propose a 750 ks observation with ACIS-S3 to employ this technique to measure gas cooling times, search for non-radiative cooling, and constrain time scales for HMXB evolution. We also propose 10 orbits of HST WFC3 observations in [SII], which with existing HST data, will allow the first comprehensive survey of the rich population of SNR expected in M51. Given the strong density contrast, we will better characterize SNR properties as a function of environment.

These temperature/density constraints will provide a critical test for competing inefficient accretion flow theories. The large angular Bondi radius of this black hole provides the *only* opportunity to perform such a test of inefficient accretion flow theory in the Chandra era and the foreseeable future.

We propose a 3-Msec HETG exposure to spatially and spectrally resolve the Bondi flow of Sgr A*. This would provide the first high spectral resolution data on Sgr A* and diffuse emission from the central pc of the galaxy. The spectrum will measure the energy and velocity width of the known Fe line from accreting matter within the Bondi radius. It will also detect plasma line emission (e.g., Si & S), if present at levels predicted by RIAF models. Polarization measurements suggest most of the matter crossing the Bondi radius does not reach the event horizon. Understanding the dynamics and thermal structure of this plasma will tell us how this matter flows in and how much and where some of it flows back out. This exposure will also permit extensive multiwavelength monitoring of Sgr A* flares.

Title: Quasar Feedback in Action: The Wide-Angle Wind of Mrk 231

PI Name: Sylvain Veilleux

In recent months, our group has discovered a ~1000-km/s outflow in the nearest post-merger quasar Mrk 231 with mass outflow rate about 3x the star formation rate. This outflow extends over several kpc and is wide-angle, thus driven by a QSO wind rather than a jet. This powerful outflow may be the long-sought "smoking gun" of quasar mechanical feedback purported to transform gas-rich mergers into red and dead galaxies. We propose a 400-ksec ACIS-S observation of Mrk 231 to permit 2D spectral mapping of this QSO wind in the X-rays. The obscuring material in Mrk 231 will act as a natural coronagraph to help us study the faint X-ray nebula around the quasar. These data will also be used to monitor the central energy source and constrain the location of the obscuring / scattering material.

We will also use a novel technique to map the velocity field of the kpc-scale gas, directly constraining the spatial extent and impact of any AGN outflow. Our observations will provide the key test of whether or not outflows in such late-type galaxies expel significant quantities of material during their hosts' transition from the blue cloud to the red sequence.

The new observations will tell us much about the intracluster medium, including the degree of turbulence, the viscosity and the mixing of metals. We will look for shocks, sound waves and other features associated with the merger. We plan to also examine gas clumping and the coronae around the central galaxies. The Coma cluster is the best multiwavelength studied cluster and the 3rd X-ray brightest. This new observation will provide an excellent legacy resource.

Title: Wolf-Rayet Winds at High Spectral Resolution

Type: LP Total Time: 450

PI Name: David Huenemoerder

The physical origin of X-ray emission in single Wolf-Rayet (WR) stars is not known. We request 450 ks on WR 6 with HETGS to establish which mechanisms operate in the winds of massive stars at the end of their evolution, shortly before a supernova or gamma-ray burst explosion. High-spectral resolution above 1 kev with HETGS is required to resolve emission lines from the hottest X-ray emitting plasma and thereby determine the location of wind structures. Principal diagnostics of X-ray emission line profiles in conjunction with our state-of-the-art stellar atmospheres code will help unravel current uncertainties in wind generation.

We propose four phase-constrained Chandra/HETGS observations of the massive, eclipsing, single-line spectroscopic binary $\delta$~Ori. Delta Ori is one of the fundamental calibrators of the mass-luminosity-radius relation in the upper HR diagram.These HETGS observations will, for the first time, provide an in-situ measurement of the distribution of the embedded, X-ray emitting shocks in the wind of an O star via radial velocity, occultation and $f/i$ ratio diagnostics, as well as determine the primary star's clumping-corrected mass loss rate. These observations will help resolve critical uncertainties in our understanding of the connection between stellar and mass loss parameters and pioneer new X-ray analysis methods in massive star astrophysics.

Title: COMPACT AND DIFFUSE X-RAY SOURCES IN THE YOUNGEST PLANETARY NEBULAE

Type: LP Total Time: 670

PI Name: Joel Kastner

The community of planetary nebula (PN) astronomers is undertaking ChanPLaNS, the first systematic X-ray survey of PNe in the solar neighborhood. ChanPlaNS is yielding such fundamental, new results as the frequency of appearance and range of X-ray spectral characteristics of X-ray-emitting PN central stars and the evolutionary timescales of wind-shock-heated bubbles within PNe. Here, we propose the next phase of the survey, in which we will observe all (24) remaining known compact (radius <= 0.4 pc), young PNe within ~1.5 kpc that have yet to be observed by Chandra. This LP represents the next step toward understanding the relationship between PN X-ray emission and PN shaping processes, and its results will have broad and profound impact on the study of binary stars and wind interactions.

Title: The Small Magellanic Cloud - A Case Study of X-ray Populations at Low Metallicity

We propose a deep survey of 11 fields (100 ks each) in the SMC probing young (10-100 Myr) stellar populations of different ages down to a luminosity limit of 2E32 erg/s, well into the regime of quiescent X-ray binaries and X-ray emitting normal stars. These observations will provide the deepest luminosity functions (XLFs) of X-ray binaries ever recorded, enabling us to: (a) directly measure their formation efficiency as a function of age; (b) address the evolution of their XLF in the 10-100Myr range, (c) constrain the duty cycles of accreting pulsars; and (d) constrain parameters relevant to their formation and evolution. We will also observe for the first time low (0.2Zo) metallicity stars, and we will search for central compact objects in SNRs, and characterize their SN type.

Title: A Legacy Study of the Relativistic Shocks of PWNe

Type: XVP Total Time: 2300

PI Name: Roger Romani

We propose deep ACIS observations of five pulsar wind nebulae (PWNe) with kyr-Myr ages. These carefully chosen targets show a high degree of axial symmetry in existing short ACIS images, so that the proposed imaging/spectroscopic studies can probe the geometry of the termination shock and the nature of the post-shock flow. Partitioning the exposure, we will also constrain instability growth and flow speed. By extending our view of PWN dynamics and evolution beyond the spectacular Crab and Vela nebulae, this legacy data set probes the mechanisms converting rotational energy to relativistic jet/torus outflow, key to astrophysical sources on many scales. Multiwavelength studies and modeling will also reveal parameters of the underlying pulsar accelerator and the wind-environment interaction.

Title: A Detailed Study of the Composite Supernova Remnant MSH 11-62

PI Name: Patrick Slane

MSH 11-62 is a remarkable example of an evolved core-collapse supernova remnant. It appears to be evolving in a wind-blown cavity created by its massive progenitor, shows evidence for energetic particles accelerated by the SNR shock and for ejecta heated by the reverse shock, and is accompanied by a neutron star powering a bright pulsar wind nebula that is apparently being disrupted by the supernova remnant reverse shock. We propose a deep Chandra observation to turn our qualitative picture of this remnant into a quantitative investigation of its ambient medium, ejecta profile, and pulsar wind nebula structure. We will use these measurements to model the evolution of the system, constrain the properties of its progenitor, and address the nature of its gamma-ray emission.

G11.2-0.3 may be the remnant of a Type IIL/b (partially stripped) supernova, in which case our observations can constrain the nature of the progenitor wind, as well as give information on shock acceleration of electrons and the evolution of the interior pulsar-wind nebula.

Title: A comparative study of two outstanding pulsar tails

Type: LP Total Time: 500

PI Name: Oleg Kargaltsev

Long pulsar tails detected in X-rays and radio are believed to result from the supersonic motion of pulsars through the ISM. The processes responsible for the tail formation, collimation, and stability are poorly understood. Short Chandra observations of two outstanding pulsar tails allowed us to characterize their general properties, but much remains to be learned about the complex physics of magnetized collimated flows. We propose much deeper observations of these two tails which show very different properties. We will measure their shapes and internal structures, perform definitive spatially-resolved spectroscopy, and study the connection with the radio tails. The results will advance our understanding of magnetized collimated outflows and their interaction with the ambient medium.

Title: ENERGY DEPENDENT X-RAY MICROLENSING AND THE STRUCTURE OF QUASARS

Type: LP Total Time: 810

PI Name: Christopher Kochanek

The structure of the X-ray emitting regions of quasars remains an open question. Using microlensing in lensed quasars, we can now constrain the sizes, finding that they are compact compared to the UV emission (2500A) with 1/2 light radii of ~10-30 gravitational radii. We propose measuring the relative sizes of the hard and soft X-ray emission, better constraining the overall X-ray sizes and comparing them to the hottest regions of the accretion disk by coarsely monitoring 6 lenses with CXO (6 epochs each) and 5 with HST/UV (2 epochs). In essence, the variability amplitudes of the X-ray/UV compared to our well-sampled optical light curves allows us to measure the sizes. We request ~2/3 (1/3) of the time in Cycle 14 (15) for a total of 864~ks (with slew tax) and 12 HST orbits.

Title: Joint Chandra/XMM/EVLA Monitoring of the Gas Cloud G2 as it Encounters Sgr A*

Type: LP Total Time: 300

PI Name: Daryl Haggard

A dense, cold cloud (G2) is on a collision course with Sgr A*, the radio source at our Galactic Center. G2 is on an eccentric orbit and already shows signs of tidal disruption by the black hole. High-energy emission from Sgr A* will likely increase significantly due to this encounter, peaking at pericenter (summer 2013). We propose simultaneous Chandra, XMM, and EVLA monitoring observations to constrain the rates and emission mechanisms of faint X-ray flares, study the radiation properties of Sgr A* as G2 breaks up and feeds gas to the central accretion flow, and detect G2 itself as it is shocked and heated. Multiwavelength observations of this encounter will have a profound impact on our understanding of radiatively inefficient accretion flows into, and outflow from, massive black holes.

Title: C-GOALS: The Chandra-RBGS Survey of a Complete Sample of Major-Merger LIRGs

PI Name: David Sanders

We propose to finish our Chandra-ACIS survey of a statistically complete sample of 87 major-merger LIRGs [log(Lir/Lsun)=11.0-12.57], from the IRAS RBGS. Our proposed Cycle-14 observations of the 29 lower-luminosity objects (11.0-11.72) will allow us to have a uniform and complete census of AGN and X-ray luminous starbursts in the nearest and brightest major-merger LIRGs, and will complement our existing Spitzer-IRAC/MIPS/IRS, HST-ACS, GALEX and Herschel observations of the same sample. The results will be used to address the following key questions: are binary AGN a common feature of these LIRGs, and if so, when and at what level is the AGN activity triggered in each nucleus? And can the fueling and growth of massive black holes be correlated in time with the merger phase?

With this observation we will push detailed studies of X-ray clusters to the edge of the current discovery limit, by measuring global temperature and Fe abundance, gas and total mass, putting strong constraints on the time formation of cool core, on the chemical enrichment time scale, on the relation between ICM and galaxy population, and deriving the best constraint to the standard Lambda-CDM model attainable at present. These results, achievable only with Chandra, are secured by a first X-ray characterization of XMMUJ0044 based on XMM data, and will constitute an unrivaled reference for distant cluster studies until the next generation of high-angular resolution X-ray satellites.

Title: A Chandra-Planck Legacy Program for Massive Clusters of Galaxies

Type: XVP Total Time: 1091

PI Name: Christine Jones

ESA's Planck Mission has provided a large, statistically representative sample of very massive clusters, detected over the full sky through their SZ effect. The Planck clusters are sufficiently X-ray bright that for all 165 z<0.35 clusters, Chandra will collect 10,000 source counts to characterize each cluster's dynamical state, including merger properties, measure cluster masses and mass proxies and define local cluster mass and temperature functions. Chandra observations will provide a benchmark at low redshifts for comparison to high redshift clusters and to cosmological N-body simulations. Our team is expert in the analysis of X-ray and SZ data and in theory, simulations, lensing, and radio studies of clusters. We plan to make our cluster analysis products available to the community.

Title: A Detailed Study of the Longest Known Ram Pressure Stripped Tail with Deep Chandra Observations of M86

Type: LP Total Time: 350

PI Name: Scott Randall

We propose deep Chandra observations of the ram pressure stripped tail in M86, the longest ram pressure stripped tail known. M86 is nearby, in the Virgo cluster (~17 Mpc), and is X-ray bright. With Chandra's high spatial resolution we will image fine detail in the tail, and map the temperature and abundance structure along the tail. We will determine the origin of the stripped gas, place limits on gas mixing in the tail with the ICM, and ultimately place constrains on ICM microphysics through comparisons with detailed hydrodynamical simulations.

Title: Resolving the nearest cold front in the sky: the cleanest experimental tool to study detailed ICM physics

Type: LP Total Time: 500

PI Name: Norbert Werner

We propose a very deep legacy-class observation of the nearest, best resolved cold front in the sky which lies 90 kpc to the North of M87. Cold fronts are known to be remarkably sharp, with gas density and temperature discontinuities several times sharper than the Coulomb mean free path. The proposed observation will provide an extraordinary improvement in resolution (resolving ~80 pc scales), allowing to study the cold front interface in unprecedented detail. Cold fronts provide a relatively simple experimental setup - a unique tool to study ICM physics. The proposed observation will place crucial constraints on fundamental physical processes shaping cold fronts, such as: growth of instabilities in the ICM, intra-cluster magnetic fields, gas velocities, conduction and viscous stresses.

Title: The COSMOS Legacy Survey

Type: XVP Total Time: 2800

PI Name: Francesca Civano

We propose the COSMOS-Legacy Survey covering the entire 1.7deg2 COSMOS/HST area to a uniform depth of ~160ks, expanding the current deep C-COSMOS area by a factor 3, with 56x50 ks pointings for a total of 2.8 Ms. This area and depth proposed are designed to detect~40 z>4, and ~4 z>5 Large Scale Structures on >15' scales, connecting luminous Chandra quasars (among over 200 z>3 quasars) and sub-mm galaxies, a method already proven in C-COSMOS. The area/depth combination also probes mini-quasars at z>7 using anistotropies of the unresolved XRB and the masses of the DM halos hosting X-ray AGN up to z~3 via autocorrelation functions on ~30' scales. Large programs with SCUBA2, NuSTAR, Subaru and Keck over the COSMOS field will identify and get redshifts for all COSMOS-Legacy sources.
