The Correlation between X-ray and UV Properties of BAL QSOs
LuLu Fan, HuiYuan Wang, Tinggui Wang +4
We compile a large sample of broad absorption lines (BAL) quasars with X-ray observations from the \xmm archive data and Sloan Digital Sky Survey Data Release 5. The sample consist…
Difference in Narrow Emission Line Spectra of Seyfert 1 and 2 galaxies
Kai Zhang, Tinggui Wang, Xiaobo Dong +1
In the unification scheme of Seyfert galaxies, a dusty torus blocks the continuum source and broad line region in Seyfert 2 galaxies. However it is not clear whether or not and to…
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…
XMM observations of BAL Quasars with polar outflows
Junxian Wang, Peng Jiang, Hongyan Zhou +3
We have selected a sample of broad absorption line (BAL) quasars which show significant radio variations, indicating the presence of polar BAL outflows. We obtained snapshot XMM ob…
The Correlation Between Spectral Index And Accretion Rate For AGN
Xue-Guang Zhang, Deborah Dultzin, Ting-Gui Wang
In this paper, we present a correlation between the spectral index distribution (SED) and the dimensionless accretion rate defined as for AGN. This quan…
