Evolution of gaseous disk viscosity driven by supernova explosion in star-forming galaxies at high redshift
Jian-Min Wang, Chang-Shuo Yan, Yan-Rong Li +5
Motivated by Genzel et al.'s observations of high-redshift star-forming galaxies, containing clumpy and turbulent rings or disks, we build a set of equations describing the dynamic…
A Systematic Analysis of Fe II Emission in Quasars: Evidence for Inflow to the Central Black Hole
Chen Hu, Jian-Min Wang, Luis C. Ho +4
Broad Fe II emission is a prominent feature of the optical and ultraviolet spectra of quasars. We report on a systematical investigation of optical Fe II emission in a large sample…
The radio luminosity, black hole mass and Eddington ratio for quasars from the Sloan Digital Sky Survey
Wei-Hao. Bian, Yan-Mei. Chen, Chen. Hu +2
We investigate the $\mbh- σ_*$ relation for radio-loud quasars with redshift in Data Release 3 of the Sloan Digital Sky Survey (SDSS). The sample consists of 3772 quasars…
Early Growth of Massive Black Holes in Quasars
J. M. Wang, Y. -M. Chen, C. -S. Yan +1
Episodic activity of quasars is driving growth of supermassive black holes (SMBHs) via accretion of baryon gas. In this Letter, we develop a simple method to analyse the duty cycle…
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…
