Many neutron stars and black holes are in binaries where the mass transfer rate onto the compact object is highly variable. X-ray observations of these transients in quiescence (Lx < 1034 erg s−1) have found that the binaries harboring black holes are much fainter than those that contain a neutron star. Narayan and collaborators postulated that the faint X-ray emission from black hole binaries ...
We discuss the imprints left by a cosmological evolution of the star formation rate (SFR) on the evolution of X-ray luminosities LX of normal galaxies, using the scheme proposed by White and Ghosh (1998, WG98), wherein the evolution of LX of a galaxy is driven by the evolution of its X-ray binary population. As indicated in WG98, the profile of LX with redshift can both serve as a diagnostic pr...
We are undertaking a survey to characterize the X-ray sources found with the Chandra X-ray observatory in a strip of fields at −3◦ < l < 3◦, b = +1.5◦ and −3◦ < l < 3◦, b = −1.5◦. This so-called Galactic Bulge Survey (GBS) targets X-ray emitting binaries in the bulge with the primary purpose of finding quiescent X-ray binaries. The aims of this survey are to quantify dynamically the mass of com...
See http://www.xassist.org/ixocat hri for figures and future updates of this catalog. NOTE – some IXO numbers have changed since the original astro-ph submission. This paper is now accepted into the ApJ Supplements, and Tables 1 and 2 comprise version 2.0 of our ROSAT HRI IXO catalog. ROSAT, and now Chandra, X-ray images allow studies of extranuclear Xray point sources in galaxies other than ou...
