Spectroscopic Classification of Extragalactic Transients from CRTS
A. J. Drake, S. G. Djorgovski, M. J. Graham +5
The Catalina Real-time Transient Survey (CRTS) carried out a public survey for optical transients between 2007 and 2019, discovering more than 16,000 transient candidates. Here we…
Deep Co-Added Sky from Catalina Sky Survey Images
Akshat Singhal, Varun Bhalerao, Ashish A. Mahabal +12
A number of synoptic sky surveys are underway or being planned. Typically they are done with small telescopes and relatively short exposure times. A search for transient or variabl…
Understanding extreme quasar optical variability with CRTS: II. Changing-state quasars
Matthew J. Graham, Nicholas P. Ross, Daniel Stern +8
We present the results of a systematic search for quasars in the Catalina Real-time Transient Survey exhibiting both strong photometric and spectroscopic variability over a decadal…
Results of a systematic search for outburst events in 1.4 million galaxies
A. J. Drake, S. G. Djorgovski, M. J. Graham +5
We present an analysis of nine years of Catalina Surveys optical photometry for 1.4 million spectroscopically confirmed SDSS galaxies. We find 717 outburst events that were not rep…
Understanding extreme quasar optical variability with CRTS: I. Major AGN flares
Matthew J. Graham, S. G. Djorgovski, Andrew J. Drake +5
There is a large degree of variety in the optical variability of quasars and it is unclear whether this is all attributable to a single (set of) physical mechanism(s). We present t…
A systematic search for close supermassive black hole binaries in the Catalina Real-Time Transient Survey
Matthew J. Graham, S. G. Djorgovski, Daniel Stern +6
Hierarchical assembly models predict a population of supermassive black hole (SMBH) binaries. These are not resolvable by direct imaging but may be detectable via periodic variabil…
