Dynamical Black Holes: Apparent Horizon Versus Energy Conditions
V Vertogradov - arxiv preprint arxiv:2410.10582, 2024 - arxiv.org
Dynamical black holes have an apparent horizon as one of their characteristics. The later
might be null, time-like, or space-like surfaces that define the evolution of a black hole. Our …

[HTML][HTML] A simple model of magnetic universe without singularity associated with a quadratic equation of state
PH Chavanis - The European Physical Journal Plus, 2024 - Springer
A model of magnetic universe based on nonlinear electrodynamics has been introduced by
Kruglov (Phys Rev D 92: 123523, 2015). This model describes an early inflation era …

Formation of regular black hole from baryonic matter
We investigate regular black hole formation through the gravitational collapse of baryonic
matter characterized by a time-and radius-dependent coefficient of equation of state. Our …

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

Regular Black Hole from gravitational collapse of dust and radiation
V Vertogradov - arxiv preprint arxiv:2501.13739, 2025 - arxiv.org
A black hole is the end state of the gravitational collapse of massive stars. However, a typical
black hole contains a singularity and to avoid singularity formation we have to violate a …
