Extremely Red Quasars from SDSS, BOSS and WISE: Classification of Optical Spectra
Nicholas P. Ross, Fred Hamann, Nadia L. Zakamska +10
Quasars with extremely red infrared-to-optical colours are an interesting population that can test ideas about quasar evolution as well as orientation, obscuration and geometric ef…
Near Infrared Spectra and Intrinsic Luminosities of Candidate Type II Quasars at 2 < z < 3.4
Jenny E Greene, Rachael Alexandroff, Michael A Strauss +10
We present JHK near-infrared (NIR) spectroscopy of 25 candidate Type II quasars selected from the Sloan Digital Sky Survey, using Triplespec on the Apache Point Observatory 3.5m te…
Gemini Long-slit Observations of Luminous Obscured Quasars: Further Evidence for an Upper Limit on the Size of the Narrow-Line Region
Kevin N. Hainline, Ryan C. Hickox, Jenny E. Greene +4
We examine the spatial extent of the narrow-line regions (NLRs) of a sample of 30 luminous obscured quasars at observed with spatially resolved Gemini-N GMOS long-s…
Similarity of ionized gas nebulae around unobscured and obscured quasars
Guilin Liu, Nadia L. Zakamska, Jenny E. Greene
Quasar feedback is suspected to play a key role in the evolution of massive galaxies, by removing or reheating gas in quasar host galaxies and thus limiting the amount of star form…
