Reverberation Mapping of Two Variable Active Galactic Nuclei: Probing the Distinct Characteristics of the Inner and Outer Broad-line Regions

Hai-Cheng Feng, Sha-Sha Li, J. M. Bai +8

Current reverberation mapping (RM) studies primarily focus on single emission lines, particularly the \hb\ line, which may not fully reveal the geometry and kinematic properties of…

How Long Will the Quasar UV/Optical Flickering Be Damped? II. the Observational Test

Guowei Ren, Shuying Zhou, Mouyuan Sun +1

The characteristic timescale at which the variability of active galactic nuclei (AGNs) turns from red noise to white noise can probe the accretion physics around supermassive black…

Velocity-resolved Reverberation Mapping of Changing-look Active Galactic Nucleus NGC 4151 during Outburst Stage. II. Four Season Observation Results

Hai-Cheng Feng, Sha-Sha Li, J. M. Bai +7

We present the results of a four-year velocity-resolved reverberation mapping (RM) campaign of the changing-look active galactic nucleus (CL-AGN) NGC 4151 during its outburst phase…

Unprecedented Continuum Time Delay Variation Phenomenon in an Active Supermassive Black Hole

Shuying Zhou, Mouyuan Sun, Hai-Cheng Feng +12

Resolving the accretion disks and broad line regions (BLRs) of active galactic nuclei (AGNs) can probe the physics behind supermassive black holes (SMBHs) fueling and weigh SMBHs.…

Stellar black holes can "stretch'' supermassive black hole accretion disks

Shuying Zhou, Mouyuan Sun, Tong Liu +3

Stellar black holes (sBHs) are widely believed to exist in the accretion disks of active galactic nuclei (AGNs). Previous studies often focus on the transient emission produced by…

How long will the quasar UV/optical flickering be damped?

Shuying Zhou, Mouyuan Sun, Zhen-Yi Cai +3

The UV/optical light curves of Active Galactic Nuclei (AGNs) are commonly described by the Damped Random Walk (DRW) model. However, the physical interpretation of the damping times…
