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…
Quasar 2175 Å dust absorbers II: Correlation analysis and relationship with other absorption line systems
Jingzhe Ma, Jian Ge, J. Xavier Prochaska +6
We present the cold neutral content (H I and C I gas) of 13 quasar 2175 Å dust absorbers (2DAs) at = 1.6 - 2.5 to investigate the correlation between the presence of the UV…
Optical Observations of LIGO Source GW 170817 by the Antarctic Survey Telescopes at Dome A, Antarctica
Lei Hu, Xuefeng Wu, I. Andreoni +30
The LIGO detection of gravitational waves (GW) from merging black holes in 2015 marked the beginning of a new era in observational astronomy. The detection of an electromagnetic si…
Carbon and Nitrogen Abundance Ratio In the Broad Line Region of Tidal Disruption Events
Chenwei Yang, Tinggui Wang, Gary J. Ferland +4
The rest-frame UV spectra of three recent tidal disruption events (TDEs), ASASSN-14li, PTF15af and iPTF16fnl display strong nitrogen emission lines but weak or undetectable carbon…
Quasar 2175 Å dust absorbers I: metallicity, depletion pattern, and kinematics
Jingzhe Ma, Jian Ge, Yinan Zhao +4
We present 13 new 2175 Å dust absorbers at z_abs = 1.0 - 2.2 towards background quasars from the Sloan Digital Sky Survey. These absorbers are examined in detail using data from th…
Reddening and He I* Absorption Lines in Three Narrow-line Seyfert 1 Galaxies
Shaohua Zhang, Hongyan Zhou, Xiheng Shi +6
We report the detection of heavy reddening and the He I* absorption lines at the AGNs' redshift in three Narrow-line Seyfert 1 galaxies: SDSS J091848.61+211717.0, SD…
Central Engine and Host Galaxy of RXJ 1301.9+2747: A Multiwavelength View of a Low-mass Black Hole Active Galactic Nuclei with Ultra-soft X-ray Emission
Xinwen Shu, Tinggui Wang, Ning Jiang +3
RXJ 1301.9+2747 is an optically identified very low mass AGN candidate with M_BH~1x10^6M_sun, which shows extremely soft X-ray emission and unusual X-ray variability in the form of…
Photoionization-driven Absorption Lines Variability in Balmer Absorption Line Quasar LBQS 1206+1052
Luming Sun, Hongyan Zhou, Tuo Ji +10
In this paper we present an analysis of absorption line variability in mini-BAL quasar LBQS 1206+1052. The SDSS spectrum demonstrates that the absorption troughs can be divided int…
The physical constraints on a new LoBAL QSO at z=4.82
Weimin Yi, Richard Green, Jin-Ming Bai +26
Very few low-ionization broad absorption line (LoBAL) QSOs have been found at high redshifts to date. One high-redshift LoBAL QSO, J0122+1216, was recently discovered at the Lijian…
Ultraviolet and Optical Emission-line Outflows in the Heavily Obscured Quasar SDSS J000610.67+121501.2: At the Scale of the Dusty Torus and Beyond
Shaohua Zhang, Hongyan Zhou, Xiheng Shi +7
Broad emission-line outflows of active galactic nuclei (AGNs) have been proposed for many years but are very difficult to quantitatively study because of the coexistence of the gra…
