Can we distinguish whether black holes have singularities or not through echoes and light rings?
Xiao-Pin Rao, Hyat Huang
A recent work [Phys. Rev. D 111, 104040] shows that the curvature singularity of a black hole can vanish at a fine-tuned mass value, which implies that regular black holes could be…
Regular black holes and their singular families
Hyat Huang, Xiao-Pin Rao
Regular black holes without curvature singularity can arise in Einstein gravity with appropriate matter energy-momentum tensor. We show that these regular solutions represent only…
Hairy Black Holes with Arbitrary Small Areas
Xiao-Ping Rao, Hyat Huang, Jinbo Yang
We obtained new hairy black hole solutions in Einstein-scalar theory, including asymptotic flat, de Sitter and anti-de Sitter black holes. The theory is inspired by Ref. [1], where…
Quasinormal modes and phase Transition of black holes
Xiaoping Rao, Bin Wang, Guohong Yang
We have studied the scalar field as well as the fermonic field perturbations in the background of the massless BTZ black holes. Comparing with the perturbation results in the gener…
