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…
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…
Discovery of 24 radio-bright quasars at using low-frequency radio observations
A. J. Gloudemans, K. J. Duncan, A. Saxena +18
High redshift quasars () that also shine brightly at radio wavelengths are unique signposts of supermassive black hole activity in the early universe. However, bright radio so…
An X-ray fading, UV brightening QSO at
Fabio Vito, Marco Mignoli, Roberto Gilli +13
Explaining the existence of SMBHs at is a persistent challenge to modern astrophysics. Multi-wavelength observations of QSOs revea…
