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…
The starburst-AGN connection: the role of young stellar populations in fueling supermassive black holes
Y. -M. Chen, J. -M. Wang, C. -S. Yan +2
Tracing the star formation history in circumnuclear regions (CNRs) is a key step towards understanding the starburst-AGN connection. However, bright nuclei outshining the entire ho…
Constraints on the star formation histories of galaxies from z~1 to z~0
Yan-Mei Chen, Vivienne Wild, Guinevere Kauffmann +5
We present a new method to estimate the average star formation rate per unit stellar mass (SSFR) of a stacked population of galaxies. We combine the spectra of 600-1000 galaxies wi…
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…
