Abstract

Using the Panchromatic Hubble Andromeda Treasury (PHAT) Program and Chandra X-Ray Observatory, we have acquired archival data from ~1/3 of Andromeda Galaxy to study the properties of the X-ray sources. Only a small fraction (~1/3) of the X-ray sources within Andromeda have been classified. We determined a total of 799 x-ray sources with 781 of them containing more than one counterpart. We present preliminary analysis of the archival data including color-magnitude diagrams, x-ray spectral analysis, and theoretical modeling that help us determine what these sources are.
