Fast Inflow Directly Feeding Black Hole Accretion Disk in Quasars
Hongyan Zhou, Xiheng Shi, Weimin Yuan +21
Quasars are high-luminosity active galactic nuclei believed to be powered by accretion of interstellar matter onto a super-massive black hole (SMBH) therein. Most of the observed e…
An Intercomparison Study of Two Proximate Damped Ly Systems with Residual Flux upon the Ly Absorption Trough toward Quasars
Xiaoyi Xie, Hongyan Zhou, Xiang Pan +6
In this paper, we present an intercomparison study of two quasars, SDSS J145618.32+340037.2 and SDSS J215331.50-025514.1, which have proximate damped Lya systems (PDLAs) with resid…
Reprocessed emission from warped accretion discs induced by the Bardeen-Petterson effect
Sheng-Miao Wu, Lei Chen, Feng Yuan
The broad Balmer emission-line profiles resulting from the reprocessing of UV/X-ray radiation from a warped accretion disc induced by the Bardeen-Petterson effect are studied. We a…
Steady state solution of warped accretion discs
Lei Chen, Shengmiao Wu, Feng Yuan
We consider a thin accretion disc warped due to the Bardeen-Petterson effect, presenting both analytical and numerical solutions for the situation that the two viscosity coefficien…
Broad reprocessed Balmer emission from warped accretion discs
Sheng-Miao Wu, Ting-Gui Wang, Xiao-Bo Dong
Double peaked broad emission lines in active galactic nuclei are generally considered to be formed in an accretion disc. In this paper, we compute the profiles of reprocessing emis…
Iron line profiles and self-shadowing from relativistic thick accretion discs
Sheng-Miao Wu, Ting-Gui Wang
We present Fe Kalpha line profiles from and images of relativistic discs with finite thickness around a rotating black hole using a novel code. The line is thought to be produced b…
