Obscured Quasars at High Redshift [abstract]

The dominant sources of energy production in the universe are fusion in stars and gravitational accretion onto supermassive black holes. The tight correlation between nuclear black hole mass and bulge mass implies the processes are intimately connected. However, identifying an unbiased census of black holes in the universe remains challenging, hampering our ability to fully probe this connection. Furthermore, the spectrum of the X-ray background, which is significantly harder than that of bright, optically-selected quasars, requires a large population of heavily-obscured AGN. Only a handful of luminous examples of this population had been identified prior to recent years. Using data from wide-area surveys with the Spitzer Space Telescope, the Chandra X-Ray Observatory and the Wide-field Infrared Survey Explorer (WISE), we have uncovered a large population of heavily obscured, luminous quasars. I discuss the properties of this population, the relative merits of selection at different wavelengths, and how this population relates to unified models of active galaxies. I will also highlight other exciting science enabled by these wide-area, multi-wavelength surveys, and conclude with future prospects with the upcoming NuSTAR mission, scheduled for launch in February 2012.
