Properties of a Previously Unidentified Instrumental Signature in that was Confused for AGN Variability
Jackeline Moreno, Rachel Buttry, John O'Brien +3
The satellite potentially provides the highest precision photometry of active galactic nuclei (AGN) available to investigate short-timescale optical variability.…
A Spitzer survey of Deep Drilling Fields to be targeted by the Vera C. Rubin Observatory Legacy Survey of Space and Time
M. Lacy, J. A. Surace, D. Farrah +60
The Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) will observe several Deep Drilling Fields (DDFs) to a greater depth and with a more rapid cadence than the main…
Placing High-Redshift Quasars in Perspective: a Catalog of Spectroscopic Properties from the Gemini Near Infrared Spectrograph -- Distant Quasar Survey
Brandon M. Matthews, Ohad Shemmer, Cooper Dix +15
We present spectroscopic measurements for 226 sources from the Gemini Near Infrared Spectrograph - Distant Quasar Survey (GNIRS-DQS). Being the largest uniform, homogeneous survey…
Characterizing Quasar CIV Emission-line Measurements from Time-resolved Spectroscopy
A. B. Rivera, G. T. Richards, P. C. Hewett +1
We use multi-epoch quasar spectroscopy to determine how accurately single-epoch spectroscopy can locate quasars in emission-line parameter space in order to inform investigations w…
Discovery of a Remarkably Powerful Broad Absorption Line Quasar Outflow in SDSS J135246.37+423923.5
Hyunseop Choi, Karen M. Leighly, Donald M. Terndrup +2
Broad absorption line (BAL) features in quasar spectra reveal an unambiguous signature of energetic outflows from central supermassive black holes, and thus BAL quasars are prime t…
The Bolometric Quasar Luminosity Function at z = 0-7
Xuejian Shen, Philip F. Hopkins, Claude-André Faucher-Giguère +4
In this paper, we provide updated constraints on the bolometric quasar luminosity function (QLF) from to . The constraints are based on an observational compilation that…
