State-dependent broadband X-ray Timing Reconfiguration in the Changing-look AGN NGC 1566
Yu Tao, Jie Tang, Xuan Wei +1
NGC 1566 has shown dramatic X-ray spectral changes during its recent changing-look outburst, but the evolution of its broadband X-ray timing properties remains poorly constrained.…

The characteristics of variability of AGNs based on the structure function
Xuan Wei, Jie Tang, Yu Tao
Variability is one of the classic features of active galactic nuclei (AGNs). The normalized structure function was applied to distinguish variability samples from OVRO, ASAS-SN and…

Timescale-dependent Optical Variability of Turn-on Changing-look Active Galactic Nuclei
Yu Tao, Jie Tang, Xuan Wei
Changing-look active galactic nuclei (CL AGNs) provide a valuable opportunity to study optical variability associated with changes in accretion state. We investigate the optical va…
