Changing-look Active Galactic Nuclei from the Dark Energy Spectroscopic Instrument. II. Statistical Properties from the First Data Release
Wei-Jian Guo, Hu Zou, Claire L. Greenwell +33
We present the identification of changing-look active galactic nuclei (CL-AGNs) from the Dark Energy Spectroscopic Instrument First Data Release and Sloan Digital Sky Survey Data R…
The NuSTAR Serendipitous Survey: the 80-month catalog and source properties of the high-energy emitting AGN and quasar population
Claire L. Greenwell, Lizelke Klindt, George B. Lansbury +32
We present a catalog of hard X-ray serendipitous sources detected in the first 80 months of observations by the Nuclear Spectroscopic Telescope Array (NuSTAR). The NuSTAR serendipi…
A population of Optically Quiescent Quasars from WISE and SDSS
Claire Greenwell, Poshak Gandhi, Daniel Stern +4
The growth of active galactic nuclei (AGN) occurs under some form of obscuration in a large fraction of the population. The difficulty in constraining this population leads to high…
Obscuration beyond the nucleus: infrared quasars can be buried in extreme compact starbursts
Carolina Andonie, David M. Alexander, Claire Greenwell +14
In the standard quasar model, the accretion disk obscuration is due to the canonical dusty torus. Here, we argue that a substantial part of the quasar obscuration can come from the…
XMM-Newton and NuSTAR Observations of an Optically Quiescent Quasar
Claire Greenwell, Poshak Gandhi, George Lansbury +3
Optically quiescent quasars (OQQs) represent a recently systematised class of infrared-luminous active galactic nuclei (AGN) which have galaxy-like optical continua. They may repre…
