Description

We present X-ray and optical analysis of 188 active galactic nuclei (AGN) identified from 497 hard X-ray (f_2.0-8.0keV_>2.7x10-15ergs/cm^2^/s) sources in 20 Chandra fields (1.5{deg}^2^) forming part of the Chandra Multiwavelength Project (ChaMP). These medium depth X-ray observations enable us to detect a representative subset of those sources responsible for the bulk of the 28keV cosmic X-ray background. Brighter than our optical spectroscopic limit, we achieve a reasonable degree of completeness (77% of X-ray sources with counterparts r'<22.5 have been classified): broad emission-line AGNs (62%), narrow emission-line galaxies (24%), absorption line galaxies (7%), stars (5%), or clusters (2%).
