AGN torus properties with WISE
Robert Nikutta, Maia Nenkova, Zeljko Ivezic +2
The Wide-field Infrared Survey Explorer (WISE) has scanned the entire sky with unprecedented sensitivity in four infrared bands, at 3.4, 4.6, 12, and 22 micron. The WISE Point Sour…
Variability-based AGN selection using image subtraction in the SDSS and LSST era
Yumi Choi, Robert R. Gibson, Andrew C. Becker +5
With upcoming all sky surveys such as LSST poised to generate a deep digital movie of the optical sky, variability-based AGN selection will enable the construction of highly-comple…
Optical variability of quasars: a damped random walk
Zeljko Ivezic, Chelsea L. MacLeod
A damped random walk is a stochastic process, defined by an exponential covariance matrix that behaves as a random walk for short time scales and asymptotically achieves a finite v…
Optical selection of quasars: SDSS and LSST
Zeljko Ivezic, W. Niel Brandt, Xiaohui Fan +3
Over the last decade, quasar sample sizes have increased from several thousand to several hundred thousand, thanks mostly to SDSS imaging and spectroscopic surveys. LSST, the next-…
All Weather Calibration of Wide Field Optical and NIR Surveys
David L. Burke, Abhijit Saha, Jenna Claver +7
The science goals for ground-based large-area surveys, such as the Dark Energy Survey, Pan-STARRS, and the Large Synoptic Survey Telescope, require calibration of broadband photome…
High-precision 2MASS JHKs light curves and other data for RR Lyrae star SDSS J015450+001501: strong constraints for non-linear pulsation models
R. Szabó, Z. Ivezić, L. L. Kiss +6
We present and discuss an extensive data set for the non-Blazhko ab-type RR Lyrae star SDSSJ015450+001501, including optical SDSS ugriz light curves and spectroscopic data, LINEAR…
