Metal-strong Inflows at the Outer-galactic-scale of a Quasar
Qiguo Tian, Lei Hao, Yipeng Zhou +6
We present an analysis of the absorption-line system in the Very Large Telescope/Ultraviolet and Visual Echelle Spectrograph spectrum at a redshift of associat…
Discovery of a Damped Ly Absorber in the Circumnuclear Zone of the FeLoBAL Quasar SDSS J083942.11+380526.3
Shengmiao Wu, Xiheng Shi, Nibedita Kalita +8
SDSS J083942.11+380526.3 () is a FeLoBAL quasar that exhibits visible Balmer absorption lines (H), implying a significant population. The quasar also shows an arr…
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…
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…
Strong Ly alpha Emission in the Proximate Damped Ly alpha Absorption Trough toward the Quasar SDSS J095253.83+011422.0
Peng Jiang, Hongyan Zhou, Xiang Pan +10
SDSS J095253.83+011422.0 (SDSS J0952+0114) was reported by Hall et al. (2004) as an exotic quasar at . In contrast to prominent broad metal--line emissions with F…
