The Pan-STARRS1 z>5.6 quasar survey II: Discovery of 55 Quasars at 5.6<z<6.5
Eduardo Banados, Jan-Torge Schindler, Bram P. Venemans +20
The identification of bright quasars at z>6 enables detailed studies of supermassive black holes, massive galaxies, structure formation, and the state of the intergalactic medium w…
Molecular Outflows in z > 6 QSO Hosts Driven by Star Formation
Kirsty M. Butler, Paul P. van der Werf, Theodoros Topkaras +4
Feedback and outflows in galaxies that are associated with a quasar phase are expected to be pivotal in quenching the most massive galaxies. However, observations targeting the mol…
The Pan-STARRS1 Quasar Survey: III. The Quasar Luminosity Function
Jan-Torge Schindler, Eduardo Bañados, Thomas Connor +9
We present the type-1 quasar luminosity function (QLF) based on the Pan-STARRS1 (PS1) quasar survey. The PS1 sample includes 125 quasars at with $…
High- Quasar Candidate Archive: A Spectroscopic Catalog of Quasars and Contaminants in Various Quasar Searches
Da-Ming Yang, Jan-Torge Schindler, Riccardo Nanni +7
We present the high- quasar candidate archive (HzQCA), summarizing the spectroscopic observations of 174 quasar candidates using Keck/LRIS, Keck/MOSFIRE, and Keck/NI…
(Nearly) Model-Independent Constraints on the Neutral Hydrogen Fraction in the Intergalactic Medium at Using Dark Pixel Fractions in Ly and Ly Forests
Xiangyu Jin, Jinyi Yang, Xiaohui Fan +10
Cosmic reionization was the last major phase transition of hydrogen from neutral to highly ionized in the intergalactic medium (IGM). Current observations show that the IGM is sign…
Detection of stellar light from quasar host galaxies at redshifts above 6
Xuheng Ding, Masafusa Onoue, John D. Silverman +41
The detection of starlight from the host galaxies of quasars during the reionization epoch () has been elusive, even with deep HST observations. The current highest redshift q…
