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…
SDSS J153636.22+044127.0 and its analogues: shocked outflows, not active binary black holes
Shaohua Zhang, Hongyan Zhou, Xiheng Shi +6
The binary emission-line system, particularly the binary broad-line emission system, is considered the most effective indicator of the black hole binary. A plausible example of suc…
An Intercomparison Study of Two Proximate Damped Ly Systems with Residual Flux upon the Ly Absorption Trough toward Quasars
Xiaoyi Xie, Hongyan Zhou, Xiang Pan +6
In this paper, we present an intercomparison study of two quasars, SDSS J145618.32+340037.2 and SDSS J215331.50-025514.1, which have proximate damped Lya systems (PDLAs) with resid…
