Deep CFHT Y-band imaging of VVDS-F22 field: I. data products and photometric redshifts
Dezi Liu, Jinyi Yang, Shuo Yuan +5
We present our deep -band imaging data of a two square degree field within the F22 region of the VIMOS VLT Deep Survey. The observations were conducted using the WIRCam instrume…
The Final SDSS High-Redshift Quasar Sample of 52 Quasars at z>5.7
Linhua Jiang, Ian D. McGreer, Xiaohui Fan +14
We present the discovery of nine quasars at identified in the Sloan Digital Sky Survey (SDSS) imaging data. This completes our survey of quasars in the SDSS footp…
The Pan-STARRS1 distant z>5.6 quasar survey: more than 100 quasars within the first Gyr of the universe
E. Bañados, B. P. Venemans, R. Decarli +33
Luminous quasars at z>5.6 can be studied in detail with the current generation of telescopes and provide us with unique information on the first gigayear of the universe. Thus far…
A survey of luminous high-redshift quasars with SDSS and WISE II. the bright end of the quasar luminosity function at z ~ 5
Jinyi Yang, Feige Wang, Xue-Bing Wu +13
This is the second paper in a series on a new luminous z ~ 5 quasar survey using optical and near-infrared colors. Here we present a new determination of the bright end of the quas…
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…
