The Unified Model of Active Galactic Nuclei: II. Evolutionary Connection
Jian-Min Wang, En-Peng Zhang
(Abbreviated) We assemble a sample composed of 243 nearby Seyfert galaxies with redshifts to test the unification scheme. The sample contains 94 BLS1s, 44 NLS1s, 36 X-r…

The Unified Model of Active Galactic Nuclei: I. Non-hidden Broad Line Region Seyfert 2 and Narrow Line Seyfert 1 Galaxies
E. -P Zhang, J. -M. Wang
The unified model of Seyfert galaxies suggests that there are hidden broad-line regions (HBLRs) in Seyfert 2 galaxies (S2s). However, there is increasing evidence for the appearanc…

Evolutionary Consequences of Dusty Tori in Active Galactic Nuclei
J. -M. Wang, E. P. Zhang, B. Luo
Deep surveys of {\em Chandra} and {\em HST} (Hubble Space Telescope) show that active galactic nucleus (AGN) populations are changing with hard X-ray luminosities. This arises an i…
