Migration Traps as Variability Attractors. I. 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…
Little Red Dots as Supermassive Counterparts of SS 433: A Hyper-Eddington Accretion Framework
Shuying Zhou, Mouyuan Sun, Xihan Ji +11
High-redshift little red dots (LRDs) are compact sources characterized by V-shaped spectral energy distributions (SEDs), broad emission lines, and often prominent Balmer breaks. Th…
Revisiting the X-ray Variability Plane of AGNs: The Significant Role of the Photon Index
Ruisong Xia, Hao Liu, Yongquan Xue +9
X-ray variability provides a powerful probe of the innermost regions of active galactic nuclei (AGNs), offering valuable insights into the accretion process and the structure of th…
X-ray Quasi-Periodic Oscillations in Active Galactic Nuclei and Their Implications for the Changing Look Phenomenon
Mouyuan Sun, Shuying Zhou, Jihong Liu +12
X-ray timing of active galactic nuclei (AGN) provides a unique probe of gas accretion onto supermassive black holes (SMBHs). Quasi-periodic oscillations (QPOs), which trace gas dyn…
