QED Effect on Black Hole Shadow
Zezhou Hu, Zhen Zhong, Peng-Cheng Li +2
In this work, taking the QED effect into account, we investigate the shadows of the static black hole with magnetic monopoles and neutral black holes in magnetic fields through the…
Novel shadows from the asymmetric thin-shell wormhole
Xiaobao Wang, Peng-Cheng Li, Cheng-Yong Zhang +1
For dark compact objects such as black holes or wormholes, the shadow size has long been thought to be determined by the unstable photon sphere (region). However, by considering th…
High spin expansion for null geodesics
Peng-Cheng Li, Minyong Guo, Bin Chen
We consider the high spin expansion for the null geodesics in the Kerr spacetime. We expand the null geodesic equation successively to higher orders in deviation from extremity. Vi…
Science with the TianQin Observatory: Preliminary results on Galactic double white dwarf binaries
Shun-Jia Huang, Yi-Ming Hu, Valeriya Korol +6
We explore the prospects of detecting of Galactic double white dwarf (DWD) binaries with the space-based gravitational wave (GW) observatory TianQin. In this work, we analyze both…
Superradiance and stability of the novel 4D charged Einstein-Gauss-Bonnet black hole
Cheng-Yong Zhang, Shao-Jun Zhang, Peng-Cheng Li +1
We investigated the superradiance and stability of the novel 4D charged Einstein-Gauss-Bonnet black hole which is recently inspired by Glavan and Lin [Phys. Rev. Lett. 124, 081301…
Constrains on the electric charges of the binary black holes with GWTC-1 events
Hai-Tian Wang, Peng-Cheng Li, Jin-Liang Jiang +3
Testing black hole's charged property is a fascinating topic in modified gravity and black hole astrophysics. In the first Gravitational-Wave Transient Catalog (GWTC-1), ten binary…
Greybody factor and power spectra of the Hawking radiation in the novel Einstein-Gauss-Bonnet de-Sitter gravity
Cheng-Yong Zhang, Peng-Cheng Li, Minyong Guo
We investigate Hawking radiation in the novel Einstein-Gauss-Bonnet gravity which is recently formulated by Glavan and Lin [Phys. Rev. Lett. 124, 081301 (2020)]. We first find…
Shadow of a Spinning Black Hole in an Expanding Universe
Peng-Cheng Li, Minyong Guo, Bin Chen
We study the influence of the cosmic expansion on the size of the shadow of a spinning black hole observed by a comoving observer. We first consider that the expansion is driven by…
