Tidal Love numbers for regular black holes
Rui Wang, Qi-Long Shi, Wei Xiong +1
Tidal Love numbers (TLNs) characterize the response of compact objects to external tidal fields and vanish for classical Schwarzschild and Kerr black holes in general relativity. N…
Quasinormal modes and grey-body factors of axial gravitational perturbations of regular black holes in asymptotically safe gravity
Qi-Long Shi, Rui Wang, Wei Xiong +1
In this paper, we present a detailed study of axial gravitational perturbations of the regular black hole solution in asymptotically safe gravity, as proposed in \cite{Bonanno:2023…
Boundary conditions of general black hole perturbations
Wei Xiong, Peng-Cheng Li
Recently, significant progress has been made in the study of black hole (BH) perturbations, both within the framework of general modified gravity theories and in complex environmen…
Quasinormal modes of spontaneous scalarized Kerr black holes
Wei Xiong, Peng-Cheng Li
Recent studies have shown that rotating black holes can undergo spontaneous scalarization, leading to deviations from general relativity in the strong-field regime. We present the…
