The End of the Road for Bulk Fields in Warped Randall-Sundrum Braneworlds
G. Alencar, R. S. Almeida, R. N. Costa Filho +2
In this manuscript we generalize Ref. [1] and derive a complete set of local consistency conditions for bulk fields in braneworld scenarios with an arbitrary number of dimensions.…
Embedding Wormholes and Dyonic Black Strings in Warped Braneworlds via Local Sum Rules
G. Alencar, T. M. Crispim, Francisco S. N. Lobo
Building on our previous work [1], where the Local Sum Rules (LSR) were established, we investigate the construction of compact objects in Randall-Sundrum braneworlds supported by…
Geometrically Regular Black Object Solutions in Lower-Dimensional Gauss-Bonnet Gravity and Its Unimodular Extension
G. Alencar, T. M. Crispim, C. R. Muniz
We investigate the construction of regular compact objects in the recently proposed lower-dimensional Einstein--Gauss--Bonnet (EGB) gravity obtained through regularized dimensional…
On regular black string spacetimes in nonlinear electrodynamics
G. Alencar, V. H. U. Borralho, T. M. Crispim +1
In this work, we investigate the coupling of General Relativity with Nonlinear Electrodynamics (NED), governed by a general Lagrangian , to address the ax…
Tidal forces around the Letelier-Alencar cloud of strings black hole
Marcos V. de S. Silva, T. M. Crispim, R. R. Landim +2
In this work, we investigate relativistic tidal forces around a black hole sourced by a cloud of strings, described by the generalized Letelier-Alencar solution. We first review th…
Black bounce as a quantum correction from string T-duality: Thermodynamics, energy conditions, and observational imprints from EHT
G. Alencar, T. M. Crispim, Diego Sáez-Chillón Gómez +1
Motivated by quantum gravity effects suggested by string theory, we investigate gravitational configurations sourced by an effective energy density inspired by T-duality. This dens…
