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…
