Topologically equivalent yet radiatively distinct orbits in EMRI system
Chao-Hui Wang, Shao-Wen Wei, Tao Zhu +1
Multiple potential wells for massive test particles, allowing distinct families of bound orbits to coexist, are a characteristic feature of certain exotic compact objects beyond ge…
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…
Gravitational equal-area law and critical phenomena of cuspy black hole shadow
Shao-Wen Wei, Chao-Hui Wang, Yu-Peng Zhang +2
The formation of a cusp on a black hole shadow is a striking signature of physics beyond the Kerr paradigm. Using the Konoplya-Zhidenko metric, a general parametrized deformation o…
Enhanced energy extraction via magnetic reconnection in Kerr-AdS spacetime
Bo Zhao, Chao-Hui Wang, Shao-Wen Wei
In this paper, we study the energy extraction from Kerr-AdS black holes following the magnetic reconnection process. The parameter space regions that satisfy the energy extraction…
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…
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…
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…
Extracting spinning wormhole energy via magnetic reconnection
Xu Ye, Chao-Hui Wang, Shao-Wen Wei
Magnetic reconnection has been extensively shown to be a promising approach to extract spinning black hole energy. In this paper, we focus on extracting spinning wormhole energy vi…
Extracting energy via magnetic reconnection from Kerr-de Sitter black holes
Chao-Hui Wang, Cheng-Qun Pang, Shao-Wen Wei
It has been recently shown that magnetic reconnection can provide us a novel mechanism to extract black hole rotational energy from a Kerr black holes. In this paper, we study the…
