The Faintest, Extremely Variable X-ray Tidal Disruption Event from a Supermassive Black Hole Binary?
Mengqiu Huang, Yongquan Xue, Shuo Li +30
Tidal disruption events (TDEs), which occur when stars enter the tidal radii of supermassive black holes (SMBHs) and are subsequently torn apart by their tidal forces, represent in…
Which active galaxies might be neutrino emitters?
Shuying Zhou, Mouyuan Sun, Guobin Mou +4
The IceCube Neutrino Observatory has identified several individual neutrino emitters associated with supermassive black hole accretion phenomena, including blazars, tidal disruptio…
Discovery of Repeating Transitions in 16 Changing-look Active Galactic Nuclei
Qian Dong, Zhi-Xiang Zhang, Wei-Min Gu +5
The repeating changing-look active galactic nuclei (RCL AGNs) exhibit multiple appearances and disappearances of broad emission lines (BELs), whose underlying mechanism remains a p…
On the Variability Features of Active Galactic Nuclei in Little Red Dots
Shuying Zhou, Mouyuan Sun, Zijian Zhang +2
The high-redshift () compact sources with ``V-shaped" spectral energy distributions (SEDs), known as Little Red Dots (LRDs), are discovered by the James Webb Space Telescope a…
Estimating Bolometric Luminosities of Type 1 Quasars with Self-Organizing Maps
Jie Chen, Linhua Jiang, Shengxiu Sun +2
We present a new method to calculate bolometric luminosities for unobscured, type 1 quasars with multi-band photometric data. Bolometric luminosity is a fundamental property to und…
Interband Lag Variability in Active Galactic Nuclei across ZTF Data from Multiple Years
Zhen-Bo Su, Zhen-Yi Cai, Hengxiao Guo +2
Interband lags in the optical continua of active galactic nuclei (AGN) have been observed over years of monitoring, yet their physical origins remain unclear. While variable interb…
A characteristic optical variability time scale in jetted active galactic nuclei: a large gamma-ray emission sample
Dingrong Xiong, Mouyuan Sun, Jun-Xian Wang +14
The variability mechanisms from jetted AGNs are still under debate. Here the damped random walk (DRW) model, implemented through Gaussian Processe (GPs), is used to fit the l…
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…
The Intermediate-Mass Black Hole Reverberation Mapping Project: First Detection of Mid-Infrared Lags in Prototypical IMBHs in NGC 4395 and POX 52
Jingbo Sun, Hengxiao Guo, Wenwen Zuo +25
The search for robust evidence of intermediate-mass black holes (IMBHs) is crucial for understanding black hole seeding process and the formation of supermassive black holes in the…
