A Good Hard Look at Cosmic Supermassive Black Hole Growth

Title: A Good Hard Look at Cosmic Supermassive Black Hole Growth
Speaker: Niel Brandt (Penn State University)
Time: 3:00 pm, January 8 (Tuesday)
Location: Lecture Hall, 3rd floor
The 7 Ms Chandra exposure on the Chandra Deep Field-South (CDF-S) has provided the most sensitive extragalactic X-ray survey by a wide margin. About 1050 X-ray sources have been detected, primarily distant active galactic nuclei (AGNs) and starburst/normal galaxies. The unmatched deep multiwavelength coverage for these sources allows superb follow-up investigations, revealing the details of supermassive black hole growth over most of cosmic time. I will briefly describe the sources in the 7 Ms CDF-S and highlight some exciting science results. The latter will include (1) evidence for black-hole vs. bulge co-evolution in the distant universe; (2) constraints on supermassive black hole growth in the first galaxies as revealed by direct detection and stacking; and (3) the discovery of a representative of a new population of faint, fast X-ray transient sources. Finally, I will discuss some future prospects for X-ray surveys of AGNs in the distant universe including the ongoing 5 Ms XMM-SERVS survey of the LSST Deep Drilling Fields and new X-ray missions.
