Constraints on the Intranight Optical Variability of Intermediate-Mass Black Hole Candidates
Wenwen Zuo, Hengxiao Guo, Wanling Liu +12
Intermediate-mass black holes (IMBHs) provide a unique regime for studying accretion variability at the low-mass end of the black hole population, yet their intranight optical vari…

Possible quasi-periodic optical oscillations of ZTF blazars
Na Wang, Guowei Ren, Shun Zhang +3
Based on the Zwicky Transient Facility (ZTF), we selected 10 blazars as our sample sources. Among these, we found four blazars (J 0923.5+4125, J 1221.3+3010, J 1503.5+4759, and J 1…

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…
