A Mid-IR Selected Changing-Look Quasar and Physical Scenarios for Abrupt AGN Fading
Daniel Stern, Barry McKernan, Matthew J. Graham +11
We report a new changing-look quasar, WISE~J105203.55+151929.5 at , found by identifying highly mid-IR variable quasars in the WISE/NEOWISE data stream. Compared to multi-…
A new physical interpretation of optical and infrared variability in quasars
Nicholas P. Ross, K. E. Saavik Ford, Matthew Graham +8
Changing-look quasars are a recently identified class of active galaxies in which the strong UV continuum and/or broad optical hydrogen emission lines associated with unobscured qu…
Overview of the DESI Legacy Imaging Surveys
Arjun Dey, David J. Schlegel, Dustin Lang +157
The DESI Legacy Imaging Surveys are a combination of three public projects (the Dark Energy Camera Legacy Survey, the Beijing-Arizona Sky Survey, and the Mayall z-band Legacy Surve…
Another unWISE Update: The Deepest Ever Full-sky Maps at 3-5 microns
A. M. Meisner, D. Lang, D. J. Schlegel
We have uniformly reprocessed ~140 terabytes of WISE and NEOWISE exposures to create the deepest ever full-sky maps at 3.4 microns (W1) and 4.6 microns (W2). Our coadds include ~4…
