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…

22 Newly Identified Repeating Changing-look AGNs and Evidence for Extreme Broad-line Region Breathing

Litao Zhu, Zhongxiang Wang, Alok C. Gupta +5

Changing-look active galactic nuclei (CL AGNs) show the appearance or disappearance of broad emission lines on timescales of years. Among them, the repeating CL (RCL) AGNs may prov…

Testing Colour-magnitude Pattern as A Method in the Search for Changing-Look AGNs

Li-tao Zhu, Zhongxiang Wang, P. U. Devanand +6

We develop a simple method to search for changing-look (CL) active galactic nucleus (AGN) candidates, and conduct a test run. In this method, optical variations of AGNs are monitor…
