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…
