Eddington ratio governs the equivalent width of MgII emission line in active galactic nuclei
Xiao-Bo Dong, Ting-Gui Wang, Jian-Guo Wang +4
We have investigated the ensemble regularities of the equivalent widths (EWs) of MgII 2800 emission line of active galactic nuclei (AGNs), using a uniformly selected sample of 2092…
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…
Partially obscured quasars in the Sloan Digital Sky Survey Early Data Release
Xiao-Bo Dong, Hong-Yan Zhou, Ting-Gui Wang +3
We have compiled a sample of 21 low redshift (z < 0.3), luminous active galactic nuclei (AGN) with large Balmer decrements (Halpha/Hbeta > 7) using the galaxy and QSO catalogs of t…
Empirical modeling of the stellar spectrum of galaxies
Cheng Li, Ting-Gui Wang, Hong-Yan Zhou +2
An empirical method of modeling the stellar spectrum of galaxies is proposed, based on two successive applications of Principal Component Analysis (PCA). PCA is first applied to th…
