The Chandra ACIS Survey of M33 (ChASeM33)
Benjamin Williams (University of Washington) , The ChASeM33 Team
We have performed a survey of M33 covering 7 ACIS-I fields, each with 200 ks of exposure. These data provide the deepest and highest resolution X-ray data for M33 available out to a projected galactocentric distance of 4 kpc. The data contain several hundred individual X-ray sources to a limiting luminosity of 1035 erg/s (0.35-8.0 keV) as well as soft diffuse emission from the hot interstellar medium. The observations were spread over multiple epochs to allow variability studies. We have performed detailed analysis on several point sources of interest, including eclipsing X-ray binaries and transients. We have also completed analysis on several diffuse sources, including supernova remnants and H II regions. An overview of the data, the results of these first detailed studies, and our plan for future work will be presented. Support for this work was provided by the National Aeronautics and Space Administration through Chandra Award Number G06-7073A issued by the Chandra X-ray Observatory Center, which is operated by the Smithsonian Astrophysical Observatory for and on behalf of the National Aeronautics Space Administration under contract NAS8-03060.
