Title: Optical Properties of Serendipitous Chandra Sources

Abstract: The Chandra Multiwavelength Project (ChaMP) has begun to amass and characterize a deep, wide-area sample of serendipitous X-ray sources detected by the Chandra X-ray Observatory, for studies of the nature, evolution, and clustering of X-ray selected AGN and galaxies. Chandra's broadband X-ray sensitivity (0.3-8keV) means that our sample is far less affected by absorption than previous optical, UV, or soft X-ray surveys, while Chandra's unique, \lsim 1\arcsec astrometry and low background enables unambiguous identification of optical counterparts to X-ray sources 10-20 times fainter than any X-ray observatory past or present. Continuation of our program of optical imaging and spectroscopy of the ChaMP sample will provide the first estimate of the intrinsic luminosity function of AGN and its evolution, and thereby constrain the history of accretion power in the universe. The large fraction of optically normal galaxies we are detecting also promises important constraints on the evolution of the global star formation rate via the X-ray binary population. The ChaMP survey products will enable a wide range of follow-up science, from studies of stellar coronal emission, to cluster evolution and cosmology.
