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…
Hbeta Profiles in Quasars: Evidence for an Intermediate-line Region
Chen Hu, Jian-Min Wang, Luis C. Ho +3
We report on a systematic investigation of the Hbeta and Fe II emission lines in a sample of 568 quasars within z < 0.8 selected from the Sloan Digital Sky Survey. The conventional…
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…
Active Galactic Nuclei with Double-Peaked Balmer Lines: I. Black Hole Masses and the Eddington ratios
Wei-Hao Bian, Yan-Mei Chen, Qu-Sheng Gu +1
Using the stellar population synthesis, we model the stellar contribution for a sample of 110 double-peaked broad-lines AGNs from the Sloan Digital Sky Survey (SDSS). The stellar v…
