Black hole with a de Sitter core: classical and quantum features

N Heidari, V Vertogradov, A Övgün - arxiv preprint arxiv:2412.05072, 2024 - arxiv.org
This work examines the implications of a black hole featuring a de Sitter core. We begin by
analyzing the spacetime and event horizon in the presence of de Sitter core. Then the partial …
