The Nature of Transition Blazars
J. J. Ruan, S. F. Anderson, R. M. Plotkin +4
Blazars are classically divided into the BL Lac (BLL) and Flat-Spectrum Radio Quasar (FSRQ) subclasses, corresponding to radiatively inefficient and efficient accretion regimes, re…
The SDSS-2MASS-WISE Ten Dimensional Stellar Color Locus
James R. A. Davenport, Zeljko Ivezic, Andrew C. Becker +6
We present the fiducial main sequence stellar locus traced by 10 photometric colors observed by SDSS, 2MASS, and WISE. Median colors are determined using 1,052,793 stars with r-ban…
Evidence for Large Temperature Fluctuations in Quasar Accretion Disks From Spectral Variability
John J. Ruan, Scott F. Anderson, Jason Dexter +1
The well-known bluer-when-brighter trend observed in quasar variability is a signature of the complex processes in the accretion disk, and can be a probe of the quasar variability…
