Quasi-periodic Eruptions from Recurrent Satellite Black Hole Transits through Magnetized Galactic Nucleus Accretion Disks
Na Wang, Jing-Tong Xing, Tong Liu +2
Quasi-periodic eruptions (QPEs) are recurrent soft X-ray flares from galactic nuclei, but their origin remains uncertain. The delayed ultraviolet (UV) counterpart detected in ZTF19…
Reincarnations of massive stars in active galactic nucleus discs
Jing-Tong Xing, Tong Liu, Jiao-Zhen She
The origin and evolution of massive stars in active galactic nucleus (AGN) discs remain uncertain. We develop a semi-analytical model that follows the evolution of an embedded core…
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…
Possible quasi-periodic optical oscillations of ZTF blazars
Na Wang, Guowei Ren, Shun Zhang +3
Based on the Zwicky Transient Facility (ZTF), we selected 10 blazars as our sample sources. Among these, we found four blazars (J 0923.5+4125, J 1221.3+3010, J 1503.5+4759, and J 1…
Variabilities driven by satellite black hole migration in AGN disks
Jing-Tong Xing, Tong Liu, Bao-Quan Huang +1
The physical origin of active galactic nucleus (AGN) variability remains unclear. Here we propose that the magnetic reconnection induced by the migration of satellite black holes (…
Nucleosynthesis contribution of neutrino-dominated accretion flows to the solar neighborhood
Yan-Qing Qi, Tong Liu, Mouyuan Sun +1
The elemental abundances of stars reflect the complex enrichment history of the galaxy. To explore and explain the metal enrichment history of the cosmic environment near our solar…
