Title: DISCRETE X-RAY SOURCES BETWEEN M 81 AND NGC 3077
PI: Martin Ward
Approved Chandra Time (Ksecs): 10.0

Abstract:
We propose a 30ks XMM-Newton observation of the tidal interaction region between the galaxies M 81 and NGC 3077. This region contains an overdensity of X-ray sources (Bi, Arp, and Zimmermann 1994) in and around the HI bridge between the galaxies. Our observation will 1) determine whether these sources are indeed associated with the M 81 system, 2) examine the physical nature of the sources (e.g. distinguish XRBs from SNRs), and 3) study differences in the X-ray populations of the tidal debris region and NGC 3077, and how this relates to the star formation history of the M81 system. We also request a 10ks Chandra HRC observation in order to obtain sub-arcsecond astrometry for the X-ray sources, which will allow us to search for optical counterparts.


Scientific Category: AGN
Title: A long X-ray look at the Piccinotti Seyfert 1 galaxy Mkn 590
PI: Maria Santos-Lleo
Approved Chandra Time (Ksecs): 100.0

Abstract:
We propose simultaneous Chandra-XMM Newton observations of Mkn 590, one of the brightest Seyfert 1 galaxies in the Piccinotti sample. We aim at obtaining a high resolution and high S/N snapshot on the X ray spectrum of this galaxy being able, at the same time, to measure its short-time scale variations. The final objective is to probe the very inner regions in this AGN. Especially, the Fe Kalpha line profile will be measured with great accuracy, which will be crucial to constrain current physical models. Chandra and XMM simultaneous observations are the only current method to allow it. HETG will constrain the profile of the narrow line core. XMM-Newton is necessary to measure the broad wings.
