The relation between the optical variability timescale, magnetic field of jets and black hole spin in active galactic nuclei
Yongyun Chen, Qiusheng Gu, Junhui Fan +5
We investigate the relationship among the jet magnetic field, black hole spin, black hole mass, Eddington ratio, and optical variability timescales in jetted active galactic nuclei…
Observational evidence for a correlation between the magnetic field of jets and star formation rate in host galaxies
Yongyun Chen, Qiusheng Gu, Junhui Fan +4
Accretion supermassive black holes in the center of active galaxies usually produce ``jets''-collimated bipolar outflows of relativistic particles. Magnetic fields near the black h…
Constraining the Binarity of Massive Black Holes in the Galactic Center and Some Nearby Galaxies via Pulsar Timing Array Observations of Gravitational Waves
Xiao Guo, Qingjuan Yu, Youjun Lu
Massive black holes (MBHs) exist in the Galactic center (GC) and other nearby galactic nuclei. As natural outcome of galaxy mergers, some MBHs may have a black hole (BH) companion.…
The Powers of Relativistic Jets depend on the Spin of Accreting Supermassive Black Hole
Yongyun Chen, Qiusheng Gu, Junhui Fan +8
Theoretical models show that the power of relativistic jets of active galactic nuclei depends on the spin and mass of the central supermassive black holes, as well as the accretion…
