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…
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…
Black bounce solutions in a realistic dark matter halo from M60*
Ednaldo L. B. Junior, José Tarciso S. S. Junior, Francisco S. N. Lobo +5
We formulate a Simpson-Visser black bounce solution embedded in a dark matter halo. The latter is modeled using an empirical density profile calibrated from observations of the ell…
Scalar-Electromagnetic Couplings as Source of Deformed Black Hole: From Shadows to Thermodynamic Topology
Ednaldo L. B. Junior, José Tarciso S. S. Junior, Francisco S. N. Lobo +5
We reconstruct a static and spherically symmetric black hole geometry originally proposed as an effective metric by identifying a consistent matter source derived from a fundamenta…
Regular Black Holes in General Relativity from Nonlinear Electrodynamics with de Sitter Cores
A. A. Araújo Filho, Ednaldo L. B. Junior, José Tarciso S. S. Junior +6
We present new regular black hole solutions in general relativity (GR) within a static, spherically symmetric framework governed by a variable equation of state, following the appr…
Black bounce solutions via nonminimal scalar-electrodynamic couplings
Daniela S. J. Cordeiro, Ednaldo L. B. Junior, José Tarciso S. S. Junior +5
Black-bounce (BB) solutions generalize the spacetimes of black holes, regular black holes, and wormholes, depending on the values of certain characteristic parameters. In this work…
Regular Bardeen black holes within non-minimal scalar-linear electrodynamic couplings
Daniela S. J. Cordeiro, Ednaldo L. B. Junior, José Tarciso S. S. Junior +6
In this paper, we demonstrate that a linear electromagnetic matter source can be constructed for regular black hole solutions, illustrated by the case of the Bardeen black hole. Ou…
Accretion dynamics in black holes with spontaneous Lorentz symmetry breaking
Daniela S. J. Cordeiro, Ednaldo L. B. Junior, José Tarciso S. S. Junior +6
We investigate the spherical accretion of various types of fluids onto a Schwarzschild-like black hole solution modified by a Kalb-Ramond field implementing spontaneous Lorentz sym…
Supermassive black hole in NGC 4649 (M60) with a dark matter halo: Impact on shadow measurements and thermodynamic properties
Francisco S. N. Lobo, Jorde A. A. Ramos, Manuel E. Rodrigues
We investigate black hole (BH) solutions embedded in a dark matter (DM) halo, modeled as extensions of the Schwarzschild metric. The DM density profile is constrained by Hubble Spa…
Relativistic structure of a supermassive black hole embedded in the dark matter halo of NGC 4649 (M60)
Francisco S. N. Lobo, Jorde A. A. Ramos, Manuel E. Rodrigues
We construct a static, spherically symmetric black hole (BH) solution embedded within a dark matter (DM) halo, formulated as a non-vacuum extension of the Schwarzschild spacetime.…
