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…

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…
