Regular black hole with sub-Planckian curvature and suppressed exponential mass inflation
Zhong-Wen Feng, Hong-Lin Liu, Yi Ling +1
We construct a static spherically symmetric regular black hole with a Minkowski core, and a degenerate inner horizon with vanishing surface gravity. The spacetime contains a non-ex…
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…
Symmetric black-to-white hole solutions with a cosmological constant
Zhong-Wen Feng, Qing-Quan Jiang, Yi Ling +2
For a system with a Hamiltonian constraint, we demonstrate that its dynamics is invariant under different choices of the lapse function, regardless of whether the Hamiltonian incor…
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…
