Feedback Limits Rapid Growth of Seed Black Holes at High Redshift
J. -M. Wang, Y. -M. Chen, C. Hu
Seed black holes formed in the collapse of population III stars have been invoked to explain the presence of supermassive black holes at high redshift. It has been suggested that a…
Captures of Red Giant Stars by Black Holes in Elliptical Galaxies: Feedback to the Hot Gas
J. -M. Wang, C. Hu
The highly disturbed hot gas in elliptical galaxies, as revealed in many {\em Chandra} X-ray images, implies a source of energy in the galactic nucleus. In some elliptical galaxies…
Evolutionary Consequences of Dusty Tori in Active Galactic Nuclei
J. -M. Wang, E. P. Zhang, B. Luo
Deep surveys of {\em Chandra} and {\em HST} (Hubble Space Telescope) show that active galactic nucleus (AGN) populations are changing with hard X-ray luminosities. This arises an i…
The Afterglows of Ultraluminous Quasars
Jian-Min Wang, Ye-Fei Yuan, Luis C. Ho
Quasars represent a brief phase in the life-cycle of most massive galaxies, but the evolutionary connection between central black holes and their host galaxies remains unclear. Whi…
