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…

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…
