Title: The History of Supermassive Black Hole Accretion from the ChaMP
Abstract: The Chandra Multiwavelength Project (ChaMP) is the widest area sensitive (logfx > -15) serendipitous X-ray survey to date, providing an invaluable probe of supermassive black hole (SMBH) accretion in 3 critical regimes; above z 3 to test the turnover of luminous optical quasars, below z 1 to track the population boom of lower luminosity AGN, and below z 0.3 to determine the fraction of galaxies hosting active accretion. These 3 nights of Gemini time with GMOS-N are ALREADY AWARDED through the Chandra/NOAO Joint time process. We proposed for i=23 NOAO Gemini-North multi-object spectroscopy in key fields to pave the L-z plane and expand our large, uniform, multi-wavelength public database.
