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…
The origin and physical mechanism of the ensemble Baldwin effect
Xiaobo Dong, Jianguo Wang, Tinggui Wang +5
We have conducted a systematic investigation of the origin and underlying physics of the line--line and line--continuum correlations of AGNs, particularly the Baldwin effect. Based…
What controls the Fe II strength in active galactic nuclei?
Xiaobo Dong, Jianguo Wang, Luis C. Ho +5
We used a large, homogeneous sample of 4178 z <= 0.8 Seyfert 1 galaxies and QSOs selected from the Sloan Digital Sky Survey to investigate the strength of Fe II emission and its co…
Exploring the Partially-obscured BLR and Partially-covered NLR
Kai Zhang, Tinggui Wang, Xiaobo Dong +2
We have conducted a series of investigations on the geometry of the reddening material in AGNs, which have important implications to the AGN unification and SMBH demography. Accord…
