Fermi detection of -rays from the radio-quiet Seyfert galaxy NGC 3281
Jun-Rong Liu, Hua Feng, Jian-Min Wang
We report the detection of significant -ray emission with -LAT from the radio-quiet Seyfert 2 galaxy NGC 3281, with a luminosity of $5.9\,(\pm 1.7)\times10^{41}\rm\,…
Fermi detection of gamma-ray Emission from the Hot Coronae of Radio-quiet Active Galactic Nuclei
Jun-Rong Liu, Jian-Min Wang, Fermi-LAT Collaboration
Relativistic jets around supermassive black holes (SMBHs) are well-known powerful -ray emitters. In absence of the jets in radio-quiet active galactic nuclei (AGNs), how the SM…
Warped accretion disks and quasars with episodic periodicity of long-term variations
Yue-Chang Peng, Jian-Min Wang, Pu Du +2
It has been found that some quasars are undergoing quasi-periodic variations (most of them with damped amplitudes) in optical bands from long-term monitoring campaigns, but how to…
Bulge Oscillation Driven by Outflows of Active Galactic Nuclei. I. Fast Outflow Case
Yue-Chang Peng, Jian-Min Wang, Yu Zhao +1
There is growing evidence for star formation inside outflows of active galactic nuclei (AGNs). The formed stars are injected into bulges and give rise to perturbation of bulges. In…
