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…
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 note on black hole masses estimated by the second moment in Narrow Line Seyfert 1 Galaxies
Wei-Hao Bian, Chen Hu, Qiu-Sheng Gu +1
The second moment of the H emission line is calculated for 329 narrow line Seyfert 1 galaxies (NLS1s) selected from the Sloan Digital Sky Survey (SDSS), which is used to calcula…
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…
Extended multiwavelength fuzz around red quasars: observational appearance of radiative feedback in action
Jian-Min Wang
Red quasars are a population, characterized by significant extinction in UV, which could be explained by absorption of dusty gas on a scale of a few kpc. We show that the enhanced…
Spins of the supermassive black hole in M87: new constraints from TeV observations
Jian-Min Wang, Yan-Rong Li, Jain-Cheng Li +1
The rapid TeV ray variability detected in the well-known nearby radio galaxy M87 implies an extremely compact emission region (5-10 Schwarzschild radii) near the horizon of the…
