Accretion dynamics of thin and thick disks in charged Kalb-Ramond black holes
Ednaldo L. B. Junior, José Tarciso S. S. Junior, Francisco S. N. Lobo +5
In this work, we investigate the accretion properties of an electrically charged, static, spherically symmetric black hole in Kalb-Ramond (KR) gravity, where a dimensionless parame…
Thin-shell wormholes in cosmic voids
Jonathan A. Rebouças, Edson Otoniel, Francisco S. N. Lobo
Cosmic voids are underdense regions that can provide an effective large-scale environment with a de Sitter-like gravitational behavior. Motivated by recent black-hole solutions emb…
Horizon-regular cross-focusing and inner-horizon obstructions in spherical f(R) gravity
Maickol Muñoz-Palma, Francisco S. N. Lobo, Jean Báez Cuevas +1
We formulate a horizon-regular double-null criterion for regular inner marginal horizons in spherically symmetric metric gravity. Using normalized outgoing and ingoing radia…
Scalaron-modified null focusing and radial monotonicity in static f(R) gravity
Maickol Muñoz-Palma, Francisco S. N. Lobo, Jean Báez Cuevas +1
We derive an exact radial monotonicity law for static, spherically symmetric spacetimes in metric \(f(R)\) gravity. For \(ds^2=A(r)dt^2-dr^2/B(r)-r^2dΩ^2\), the matter contribution…
Black bounce sourced by non-minimally coupled linear electrodynamics and a canonical scalar field through a thin shell at the throat
Ednaldo L. B. Junior, José Tarciso S. S. Junior, Francisco S. N. Lobo +5
We construct a novel class of black bounce solutions within General Relativity, sourced by a canonical scalar field non-minimally coupled to linear electrodynamics, establishing a…
Entropy dynamics in gravitational collapse: From Minkowski breaking to de Sitter thermodynamics
Francisco S. N. Lobo, Manuel E. Rodrigues
The origin of black hole entropy remains one of the deepest mysteries in modern physics. Two recent developments offer complementary perspectives on this puzzle: the entropy releas…
