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…
Exoplanets in the Antarctic Sky. I. The First Data Release of AST3-II (CHESPA) and New Found Variables within the Southern CVZ of TESS
Hui Zhang, Zhouyi Yu, Ensi Liang +37
Located at Dome A, the highest point of the Antarctic plateau, the Chinese Kunlun station is considered to be one of the best ground-based photometric sites because of its extremel…
Exoplanets in the Antarctic sky. II. 116 Transiting Exoplanet Candidates Found by AST3-II (CHESPA) within the Southern CVZ of TESS
Hui Zhang, Zhouyi Yu, Ensi Liang +37
We report first results from the CHinese Exoplanet Searching Program from Antarctica (CHESPA)---a wide-field high-resolution photometric survey for transiting exoplanets carried ou…
The First Release of the AST3-1 Point Source Catalogue from Dome A, Antarctica
Bin Ma, Zhaohui Shang, Yi Hu +35
The three Antarctic Survey Telescopes (AST3) aim to carry out time domain imaging survey at Dome A, Antarctica. The first of the three telescopes (AST3-1) was successfully deployed…
Searching for the Transit of the Earth--mass exoplanet Proxima~Centauri~b in Antarctica: Preliminary Result
Hui-Gen Liu, Peng Jiang, Xingxing Huang +21
Proxima Centauri is known as the closest star from the Sun. Recently, radial velocity observations revealed the existence of an Earth-mass planet around it. With an orbital period…
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…
Rapid Infrared Variability of Three Radio-loud Narrow-line Seyfert 1 Galaxies: A View from the Wide-field Infrared Survey Explorer
Ning Jiang, Hong-Yan Zhou, Luis C. Ho +6
Using newly released data from the Wide-field Infrared Survey Explorer, we report the discovery of rapid infrared variability in three radio-loud narrow-line Seyfert 1 galaxies (NL…
