A Good Hard Look at Growing Supermassive Black Holes in the Distant Universe |
Seminar Title | A Good Hard Look at Growing Supermassive Black Holes in the Distant Universe | | | Speaker: | Prof. Niel Brandt | | | Affiliation: | (The Pennsylvania State University) | | | When | Thursday afternoon ,Oct.27, 15:00 p.m | | | Where: | Room 212, Astronomy Building ,(NJU) | | Welcome to Attend | | | ( PMO Academic Committee & Academic Circulating committee) | | Abstract : Sensitive cosmic X-ray surveys with the Chandra, XMM-Newton, and NuSTAR observatories have revolutionized our ability to find and study distant active galactic nuclei (AGNs), the main sites of supermassive black hole growth in the Universe. I will describe some of the resulting discoveries about the demographics, physics, and ecology of AGNs. Topics covered will include the utility of deep X-ray plus multiwavelength surveys for investigating distant AGNs; evolution constraints for the typical AGNs of the distant Universe; the cosmic balance of power between supermassive black holes and stars; interactions between AGNs and their hosting galaxies; and the AGN content of newly forming galaxies. I will end by discussing some key outstanding questions and new observations and missions that aim to answer them. |
