Non-Stationary Wormholes and Matter Source Reconstruction in General Relativity
Geová Alencar, Tiago Crispim, Roberta Dárlla +1
We investigate non-stationary wormhole geometries in General Relativity embedded in evolving cosmological backgrounds. We employ a Simpson-Visser-like regularization of the tempora…
From massless wormholes to massive black bounces: Shadows and multiple light rings
G. Alencar, Kirill A. Bronnikov, T. M. Crispim +2
We develop a general framework for constructing massive black bounce geometries from massless wormhole seeds by introducing a position-dependent mass function while preserving the…
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…
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…
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.…
