Imprints of the Lorentz-symmetry breaking on the precessing jet nozzle of M87*
Tao-Tao Sui, Xiang-Cheng Meng, Xin-Yang Wang
The approximately 11-year jet precession period observed in M87* strongly suggests that the supermassive rotating black hole with a tilted accretion disk, which could provide a pow…
Magnetic field effects on spherical orbit in Kerr-Bertotti-Robinson spacetime: constraints from jet precession of M87*
Chao-Hui Wang, Xiang-Cheng Meng, Shao-Wen Wei
The recently reported precession period of about years of the M87* jet provides a sensitive probe of strong field gravity and the electromagnetic environment in the immedia…
Equatorial periodic orbits and gravitational waveforms in a black hole free of Cauchy horizon
Chao-Hui Wang, Xiang-Cheng Meng, Yu-Peng Zhang +2
In this paper, we study the periodic orbits and gravitational wave radiation in an extreme mass ratio inspiral system, where a stellar-mass object orbits a supermassive black hole…
Precession of spherical orbits for the spacetime without symmetry induced by NUT charge
Xiang-Cheng Meng, Shan-Ping Wu, Shao-Wen Wei
Astrophysical evidence has hinted at the existence of a nonzero NUT charge, which breaks the symmetry of spacetime and induces novel features in geodesics. In this w…
Imprints of black hole charge on the precessing jet nozzle of M87*
Xiang-Cheng Meng, Chao-Hui Wang, Shao-Wen Wei
The observed jet precession period of approximately 11 years for M87* strongly suggests the presence of a supermassive rotating black hole with a tilted accretion disk at the cente…
