Correspondence of eikonal quasinormal modes and unstable fundamental photon orbits for Kerr-Newman black hole
Peng-Cheng Li, Tsai-Chen Lee, Minyong Guo +1
In this work, we study the relation of the eikonal quasinormal modes (EQNMs) and the unstable fundamental photon orbits (UFPOs) in the Kerr-Newman spacetime. We find that in the ei…
Tight constraints on Einstein-dilation-Gauss-Bonnet gravity from GW190412 and GW190814
Hai-Tian Wang, Shao-Peng Tang, Peng-Cheng Li +2
Gravitational-wave (GW) data can be used to test general relativity in the highly nonlinear and strong field regime. Modified gravity theories such as Einstein-dilation-Gauss-Bonne…
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…
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…
