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…
Black hole spacetimes with dark matter spikes: Energy-momentum tensor and backreaction effects
Wei Xiong, Peng-Cheng Li
We study the energy-momentum tensor of a dark matter (DM) spike formed during the adiabatic growth of a black hole embedded in a DM halo, and investigate its backreaction on the sp…
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…
