CIV emission line properties and uncertainties in black hole mass estimates of z ~ 3.5 quasars
Wenwen Zuo, Xue-Bing Wu, Xiaohui Fan +5
Using a high luminosity ( erg s), high redshift () quasar sample of 19 quasars with optical and near-infrared spectros…
Spectroscopy of broad absorption line quasars at -- I: evidence for quasar winds shaping broad/narrow emission line regions
Weimin Yi, Wenwen Zuo, Jinyi Yang +6
We present an observational study of 22 broad absorption line quasars (BAL QSOs) at based on optical/near-IR spectroscopy, aiming to investigate quasar wind…
The Evolution of Chemical Abundance in Quasar Broad Line Region
Fei Xu, Fuyan Bian, Yue Shen +3
We study the relation between the metallicity of quasar broad line region (BLR) and black hole (BH) mass () and quasar bolometric luminosit…
Quasar Photometric Redshifts and Candidate Selection: A New Algorithm Based on Optical and Mid-Infrared Photometric Data
Qian Yang, Xue-Bing Wu, Xiaohui Fan +8
We present a new algorithm to estimate quasar photometric redshifts (photo-s), by considering the asymmetries in the relative flux distributions of quasars. The relative flux mo…
Near-IR spectroscopy of luminous LoBAL quasars at 1<z<2.5
Andreas Schulze, Malte Schramm, Wenwen Zuo +7
We present near-IR spectroscopy of 22 luminous low-ionization broad absorption line quasars (LoBAL QSOs) at redshift 1.3<z<2.5, with 12 objects at z~1.5 and 10 at z~2.3. The spectr…
A survey of luminous high-redshift quasars with SDSS and WISE. I. target selection and optical spectroscopy
Feige Wang, Xue-Bing Wu, Xiaohui Fan +14
High-redshift quasars are important tracers of structure and evolution in the early universe. However, they are very rare and difficult to find when using color selection because o…
