Multimessenger pulsar timing array constraints on supermassive black hole binaries traced by periodic light curves
Chengcheng Xin, Chiara M. F. Mingarelli, Jeffrey S. Hazboun
Supermassive black hole binary systems (SMBHBs) emitting gravitational waves may be traced by periodic light curves. We assembled a catalog of 149 such periodic light curves, and u…
Correlation between Optical and UV Variability of Quasars
Chengcheng Xin, Maria Charisi, Zoltán Haiman +1
The variability of quasars across multiple wavelengths is a useful probe of physical conditions in active galactic nuclei. In particular, variable accretion rates, instabilities, a…
Testing the relativistic Doppler boost hypothesis for the binary candidate quasar PG1302-102 with multi-band Swift data
Chengcheng Xin, Maria Charisi, Zoltan Haiman +4
The bright quasar PG1302-102 has been identified as a candidate supermassive black hole binary from its near-sinusoidal optical variability. While the significance of its optical p…
