Time Variation of Fine-Structure Constant Constrained by [O III] Emission-Lines at 1.1<z<3.7
Ge Li, Luming Sun, Xiangjun Chen +1
[O III]4960,5008 doublet are often the strongest narrow emission lines in starburst galaxies and quasi-stellar objects (QSOs), and thus are a promising probe to possible variat…
Feeding the Accretion Disk from the Dusty Torus in a Reddened Quasar
Ge Li, Xiheng Shi, Qiguo Tian +4
We present here a detailed analysis of an unusual absorption line system in the quasar SDSS J122826.79+100532.2. The absorption lines in the system have a common redshifted velocit…
A Mid-infrared Flare in the Active Galaxy MCG-02-04-026: Dust Echo of a Nuclear Transient Event
Luming Sun, Ning Jiang, Tinggui Wang +8
We report the discovery of a mid-infrared (MIR) flare using WISE data in the center of the nearby Seyfert 1.9 galaxy MCG-02-04-026. The MIR flare began in the first half of 2014, p…
Fast Inflow Directly Feeding Black Hole Accretion Disk in Quasars
Hongyan Zhou, Xiheng Shi, Weimin Yuan +21
Quasars are high-luminosity active galactic nuclei believed to be powered by accretion of interstellar matter onto a super-massive black hole (SMBH) therein. Most of the observed e…
