Talk Title: X-rays from the First Massive Black Holes
Abstract: X-ray studies of high-redshift (z > 4) active galaxies have advanced dramatically over the past few years, largely due to complementary results from Chandra and XMM-Newton. I will review these results and discuss their implications for the first massive black holes and their young host galaxies. In particular, I will focus on constraints on quasar energetics and environments from a systematic Chandra and XMM-Newton study of the highest redshift known quasars, mostly found by the Sloan Digital Sky Survey. I will also present results from the Chandra Deep Field-North and Extended Chandra Deep Field-South surveys which (1) allow study of the X-ray emission properties of moderate-luminosity active galaxies at z > 4, and (2) constrain the number density of high-redshift active galaxies with implications for reionization. Finally, I will describe how these studies are laying crucial observational groundwork for future missions including Constellation-X, XEUS, and Generation-X.
