The QUEST-La Silla AGN Variability Survey: selection of AGN candidates through optical variability
P. Sánchez-Sáez, P. Lira, R. Cartier +6
We used data from the QUEST-La Silla Active Galactic Nuclei (AGN) variability survey to construct light curves for 208,583 sources over deg, with a a limiting magnitu…
The QUEST-La Silla AGN variability survey: connection between AGN variability and black hole physical properties
P. Sánchez-Sáez, P. Lira, J. Mejía-Restrepo +5
We present our statistical analysis of the connection between active galactic nuclei (AGN) variability and physical properties of the central supermassive black hole (SMBH). We con…
The interacting late-type host galaxy of the radio-loud narrow-line Seyfert 1 IRAS 20181-2244
M. Berton, E. Congiu, S. Ciroi +15
Narrow-line Seyfert 1 galaxies (NLS1s) are a class of active galactic nuclei (AGN) which are known to be one of the few sources of rays, which originate in a relativistic beame…
Near Infrared Variability of obscured and unobscured X-ray selected AGN in the COSMOS field
P. Sánchez, P. Lira, R. Cartier +9
We present our statistical study of near infrared (NIR) variability of X-ray selected Active Galactic Nuclei (AGN) in the COSMOS field, using UltraVISTA data. This is the largest s…
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)…
The QUEST-La Silla AGN Variability Survey
Régis Cartier, Paulina Lira, Paolo Coppi +7
We present the characterization and initial results from the QUEST-La Silla AGN variability survey. This is an effort to obtain well sampled optical light curves in extragalactic f…
