Migration Traps as Variability Attractors: Optical/UV Signatures of Embedded Stellar-Mass Black Holes in Active Galactic Nucleus Disks
Jing-Tong Xing, Tong Liu, Mouyuan Sun +5
We investigate whether embedded stellar-mass black holes (sBHs) in active galactic nucleus (AGN) disks can leave observable optical/UV variability signatures through migration-trap…
Reduced Incidence of Little Red Dots at z < 3 from Number Density and Halo Mass Evolution
Chenxuan Zhang, Huanian Zhang, Qingwen Wu +2
An intriguing puzzle in extragalactic astronomy is the scarcity of Little Red Dots (LRDs) at , compared to their higher abundance at earlier cosmic epochs. To investigate th…
Numerical modeling the mass feeding rates onto accretion-modified stars embedded within AGN disks
Yang Luo, Jian-Min Wang
Accretion disks surrounding supermassive black holes can potentially form stars within the self-gravitating region. These stars undergo high accretion rates because of the dense en…
A New Interpretation for the Hot Corona in Active Galactic Nuclei
Yu Zhao, Yan-Rong Li, Jian-Min Wang
This work attempts to provide a new interpretation for the hot corona in active galactic nuclei (AGNs). A thin parabolic magnetic reconnection layer, anchored at the innermost disk…
Nuclear burning in an accretion flow around a stellar-mass black hole embedded within an AGN disk
Zifan Tang, Yang Luo, Jian-Min Wang
A stellar-mass black hole, embedded within the accretion disk of an active galactic nuclei (AGN), has the potential to accrete gas at a rate that can reach approximately $\sim 10^9…
Gleeok's Fire-breathing: Triple Flares of AT 2021aeuk within Five Years from the Active Galaxy SDSS J161259.83+421940.3
Dong-Wei Bao, Wei-Jian Guo, Zhi-Xiang Zhang +12
We present a noteworthy transient AT 2021aeuk exhibiting three distinct optical flares between 2018 and 2023. It is hosted in a radio-loud narrow-line Seyfert 1 (NLSy1) galaxy, wit…
