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 $z_{a} = 3.1448$ associat…

Discovery of a Damped Ly $α$ 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 ( $z = 2.315$ ) is a FeLoBAL quasar that exhibits visible Balmer absorption lines (H $α$ ), implying a significant $n = 2$ population. The quasar also shows an arr…
