[37.03] X-ray Quasars, Buried AGN, and Clusters from the ChaMP

P. J. Green (Harvard-Smithsonian Center for Astrophysics), ChaMP Collaboration

The Chandra Multiwavelength Project (ChaMP) is a serendipitous survey of the X-ray sky, covering about 14 sq.deg. in the X-ray flux range of -13 to -15.5 (log 0.5-2 keV flux, cgs) and will include about 8000 sources, with optical IDs for 75%. To 21st mag in the optical, about 70% of these are newly discovered active galactic nuclei (AGN). Using Chandra archival data, we span X-ray flux limits between those reached by previous satellites and those of the deepest small-area Chandra and XMM surveys, allowing study of larger samples of rare objects such as absorbed AGN, groups and clusters of galaxies. We present early results from our own optical (SDSS filter) imaging and spectroscopy, highlight some of the unique sources we are uncovering, and offer an introduction to ChaMP data available on the web.

We gratefully acknowledge the financial support of NASA grant: AR1-2003X (Chandra).
