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…
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…
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…
