A characteristic optical variability time scale in jetted active galactic nuclei: a large gamma-ray emission sample
Dingrong Xiong, Mouyuan Sun, Jun-Xian Wang +14
The variability mechanisms from jetted AGNs are still under debate. Here the damped random walk (DRW) model, implemented through Gaussian Processe (GPs), is used to fit the l…

SMBH binary candidate PKS J2134-0153: Possible multi-band periodic variability and inter-band time lags
Guowei Ren, Mouyuan Sun, Nan Ding +2
Studying the periodic flux-variation behavior of blazars is vital for probing supermassive black hole binaries and the kinematics of relativistic jets. In this work, we report the…
