Exact Dynamical Regular Black Holes from Generalized Polytropic Matter
Dmitriy Kudryavcev, Yi Ling, Vitalii Vertogradov
We present a class of exact, dynamical, and fully analytic solutions describing regular black holes formed via the gravitational collapse of matter obeying a generalized polytropic…

Linking interior curvature to observable shadows: A case study of nonsingular black holes
Ming-Xin Li, Jin Pu, Yi Ling +1
We establish a direct connection between the interior curvature structure of nonsingular black holes (BHs) with a Minkowski core and their observable optical signatures. By classif…

Quasinormal modes of regular black holes with sub-Planckian curvature and Minkowskian core
Chen Tang, Yi Ling, Qing-Quan Jiang +1
We investigate the perturbation of the scalar field as well as the electromagnetic field over a sort of regular black holes which are characterized by the sub-Planckian curvature a…
