Gravity/thermodynamics correspondence via black hole shadows
Shao-Wen Wei, Yu-Xiao Liu
The shadow of a black hole serves as a pristine window into the strong-gravity regime, with cuspy feature emerging as a smoking-gun signature of physics beyond the Kerr paradigm. I…
Interior geometry of black holes as a probe of first-order phase transition
Zi-Qiang Zhao, Zhang-Yu Nie, Shao-Wen Wei +2
Traditional diagnostics of black hole phase transitions rely on thermodynamic quantities defined at the event horizon or asymptotic boundary. Here, we demonstrate that the near-sin…
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…
Effects of magnetic fields on spinning test particles orbiting Kerr-Bertotti-Robinson black holes
Yu-Kun Zhang, Shao-Wen Wei
In this paper, we study the kinematic effects of spinning test particles orbiting the Kerr-Bertotti-Robinson black hole. Employing with the Mathisson-Papapetrou-Dixon equations, we…
A new type of multi-branch periodic orbits in dyonic black holes
Chao-Hui Wang, Yu-Peng Zhang, Tao Zhu +1
We investigate bound timelike periodic orbits in dyonic black hole spacetimes arising from quasi-topological electromagnetism. By varying the coupling parameter , we show that…
