A Quasar Discovered at redshift 6.6 from Pan-STARRS1
Ji-Jia Tang, Tomotsugu Goto, Youichi Ohyama +11
Luminous high-redshift quasars can be used to probe of the intergalactic medium (IGM) in the early universe because their UV light is absorbed by the neutral hydrogen along the lin…
Mg II Absorption at 2<z<7 with Magellan/FIRE, III. Full Statistics of Absorption Towards 100 High-Redshift QSOs
Shi-Fan S. Chen, Robert A. Simcoe, Paul Torrey +12
We present final statistics from a survey for intervening MgII absorption towards 100 quasars with emission redshifts between and . Using infrared spectra from Mag…
No overdensity of Lyman Alpha Emitting Galaxies around a quasar at z~5.7
C. Mazzucchelli, E. Bañados, R. Decarli +4
Bright quasars, observed when the Universe was less than one billion years old (z>5.5), are known to host massive black holes (~10 M), and are thought to reside in…
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…
