Absorption of 10 Gev--1 Tev Gamma Rays by Radiation from Broad-Line Region in 3C 279
H. T. Liu, J. M. Bai, L. Ma
In this paper, we study the photon-photon pair production optical depth for 10 GeV--1 TeV gamma rays from 3C 279 due to the diffuse radiation of broad-line region (BLR). Assuming a…

Tests for Standard Accretion Disk Models by Variability in Active Galactic Nuclei
H. T. Liu, J. M. Bai, X. H. Zhao +1
In this paper, standard accretion disk models of AGNs are tested using light curves of 26 objects well observed for reverberation mapping. Time scales of variations are estimated b…
