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

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

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.

Title: SPATIALLY RESOLVED LETG SPECTROMETRY OF SNR1987A

PI Name: Richard McCray

We will obtain a spatially resolved LETG spectrum of the newborn supernova remnant SNR1987A. This observation will complement a 270 ks GTO observation of SNR1987A with the HETG. 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.

Title: A Deep Chandra Observation of the Tycho Supernova Remnant

PI Name: John Hughes

We propose to obtain a very deep observation of the Tycho supernova remnant. Our observational goals include measuring the angular expansion of the forward shock and contact discontinuity, investigating the nature and origin of Fe-rich ejecta knots, and studying the spectral structure of the forward shock. For the expansion measurement we will compare to an existing Chandra observation taken in cycle 4 that was specifically optimized for subsequent expansion measurements. Tycho is the ideal remnant for studies of cosmic-ray modified dynamics and investigating key features of Type Ia supernova physics.

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

PI Name: You-Hua Chu

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.

Title: Jets, Bubbles, Binaries, and Hot Gas: A Deep Observation of Centaurus A

PI Name: Ralph Kraft

We propose to observe Centaurus A, the nearest radio galaxy and the nearest massive early-type galaxy, for 1.2 Ms. We will probe the particle acceleration processes of the jet to an unprecedented sensitivity, by measuring its spectrum and morphology on the scale of radiative energy losses. 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

PI Name: David Sanders

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 ?

Title: The Definitive Chandra Observations of NGC 4258

PI Name: Michael Nowak

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: A Complete Baryon Census in a Nearby Galaxy Group

PI Name: John Mulchaey

We propose an ACIS-I mosaic of the NGC2563 group to study the X-ray properties of the group galaxies out to the virial radius of the system. The proposed observations will provide important observational constraints on the mechanisms that drive galaxy evolution in groups by allowing us to study how the properties of galaxies vary with distance from the group center, IGM and galaxy density. The Chandra data will allow us to study the hot ISM halos of individual galaxies as well as the more extended intragroup medium component, which combined with our existing optical and HI data will provide a complete census of all of the major baryonic components in the group.

Title: THE CHANDRA-COSMOS SURVEY

PI Name: Martin Elvis

We propose the Chandra-COSMOS survey which will provide an unprecedented combination of contiguous area, depth and resolution. 36 densely tiled observations will cover the central 0.7 sq.deg. COSMOS field to a uniform 200ksec depth. COSMOS explores the coupled evolution of galaxies, dark matter halos and AGNs (massive black holes) largely free of cosmic variance. COSMOS is a comprehensive survey including: HST, Spitzer, Subaru, VLT, Magellan, VLA, MAMBO, GALEX, & potentially EVLA & ALMA. Chandra resolution & sensitivity enables the study of large scale phenomena: (1) influence of the surrounding environment; (2) interaction between galaxies; (3) influence of groups and clusters: (4) BH growth and census; (5) star formation and stellar populations; (6) feedback from starbursts and AGNs.

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

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

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.
