[102.01] Supermassive Black Holes in the Distant Universe

A. J. Barger (U. Wisconsin and U. Hawaii)

High energy X-ray observations reveal the accretion of matter onto supermassive black holes in the distant Universe, even when they are highly obscured by gas and dust. With the Chandra X-ray Observatory, spectacular advances are being made in obtaining a cosmic census of these black holes. Multiwavelength follow-up observations allow us to reconstruct a time history of the accretion. I will also present new observations of faint active galactic nuclei at the very highest redshifts (z>5).

I gratefully acknowledge research support from NSF, NASA, the Alfred P. Sloan Foundation, and the Wisconsin Alumni Research Foundation.
