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…
Quantum-inspired wormholes from String T-Duality
Francisco S. N. Lobo, Manuel E. Rodrigues
The intrinsic non-perturbative features of string-theoretic corrections, particularly those arising from T-duality, have been shown to naturally introduce an effective ultraviolet…
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.…
