The Redshifted Hydrogen Balmer and Metastable He I Absorption Line System in Mini-FeLoBAL Quasar SDSS J112526.12+002901.3: A Parsec Scale Accretion Inflow?
Xi-Heng Shi, Peng Jiang, Hui-Yuan Wang +4
The accretion of interstellar medium onto the central super massive black holes is widely accepted as the source of the gigantic energy released by the active galactic nuclei. But…
The Extreme Ultraviolet Variability of Quasars
Brian Punsly, Paola Marziani, Shaohua Zhang +2
We study the extreme ultraviolet (EUV) variability (rest frame wavelengths 500 - 920 ) of high luminosity quasars using HST (low to intermediate redshift sample) and SDSS (high…
Broad Balmer Absorption Line Variability: Evidence of Gas Transverse Motion in the QSO SDSS J125942.80+121312.6
Xiheng Shi, Hongyan Zhou, Xinwen Shu +6
We report on the discovery of broad Balmer absorption lines variability in the QSO SDSS J125942.80+121312.6, based on the optical and near-infrared spectra taken from the SDSS-I, S…
Strong Ly alpha Emission in the Proximate Damped Ly alpha Absorption Trough toward the Quasar SDSS J095253.83+011422.0
Peng Jiang, Hongyan Zhou, Xiang Pan +10
SDSS J095253.83+011422.0 (SDSS J0952+0114) was reported by Hall et al. (2004) as an exotic quasar at . In contrast to prominent broad metal--line emissions with F…
