AGN Populations in Large Volume X-ray Surveys: Photometric Redshifts and Population Types found in the Stripe 82X Survey
Tonima Tasnim Ananna, Mara Salvato, Stephanie LaMassa +16
Multi-wavelength surveys covering large sky volumes are necessary to obtain an accurate census of rare objects such as high luminosity and/or high redshift active galactic nuclei (…
The Hunt for Red Quasars: Luminous Obscured Black Hole Growth Unveiled in the Stripe 82 X-ray Survey
Stephanie M. LaMassa, Eilat Glikman, Marcella Brusa +18
We present results of a ground-based near-infrared campaign with Palomar TripleSpec, Keck NIRSPEC, and Gemini GNIRS to target two samples of reddened active galactic nucleus (AGN)…
Peering through the dust II: observations of two additional FIRST-2MASS red quasars
Eilat Glikman, Stephanie LaMassa, Enrico Piconcelli +2
We obtained observations of two highly luminous dust-reddened quasars, F2M1113+1244 and F2M1656+3821, that appear to be in the early, transitional phase predicted by m…
Understanding extreme quasar optical variability with CRTS: I. Major AGN flares
Matthew J. Graham, S. G. Djorgovski, Andrew J. Drake +5
There is a large degree of variety in the optical variability of quasars and it is unclear whether this is all attributable to a single (set of) physical mechanism(s). We present t…
Extreme Variability in a Broad Absorption Line Quasar
Daniel Stern, Matthew J. Graham, Nahum Arav +9
CRTS J084133.15+200525.8 is an optically bright quasar at z=2.345 that has shown extreme spectral variability over the past decade. Photometrically, the source had a visual magnitu…
