Revealing the Physical Driver of the Baldwin Effect: Gas Density in the Broad-Line Region
Wen-Qiang Liang, Zhi-Fu Chen, Rui-Jing Lu +8
The Baldwin effect --- the inverse correlation between the equivalent width of emission lines and the continuum luminosity in active galactic nuclei (AGNs) --- has been known for n…
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…
A comparative study of ultraluminous infrared galaxies in the IRAS and SDSS Surveys
Shaohua Zhang, Zhijian Luo, Xiheng Shi +3
We present a comprehensive study of Ultraluminous Infrared Galaxies (ULIRGs), leveraging data from the IRAS Faint Source Catalogue (FSC) and the spectroscopic catalog in the Sloan…
The 2175 Å~ Bump Features in FeLoBAL Quasars: One Indicator of MW-like Dust in the Nuclear Region of Quasar
Shaohua Zhang, Jian Ge, Tuo Ji +8
To investigate the properties of dust in the nuclear region of quasars, we explored the extinction curves of the iron low-ionization broad absorption line (FeLoBAL) quasar SDSS J16…
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…
