The physical mechanism for two rapid changing-look AGNs: SDSS J0225+0030 and SDSS J1723+5504
Shuang-Liang Li, Xinwu Cao, Wei-Min Gu
SDSS J0225+0030 and SDSS J1723+5504 are two turn-on changing-look active galactic nuclei (CL AGNs) with transition timescales shorter than one year. Such short timescales pose a ch…

A Sandwich Model for Changing-Look AGNs
Qian-Qi Ma, Wei-Min Gu, Zhen-Yi Cai +4
The spectral variability of changing-look active galactic nuclei (CL-AGNs) occurred on timescales of years to tens of years, posing a significant challenge to the standard thin dis…
