Distinguishing wormholes via Einstein rings and global curvature
M. B. Cruz, C. R. Muniz, R. M. P. Neves +1
In this work, we investigate the gravitational lensing properties of a static Ellis-Bronnikov wormhole embedded in a curved Friedmann-Lemaître-Robertson-Walker (FLRW) universe. By…
Traversable Casimir Wormholes with Gravitational Memory
Jonathan A. Rebouças, Francisco Bento Lustosa, Celio R. Muniz
We investigate a class of traversable wormhole geometries supported by an effective Casimir source corrected by gravitational memory. The construction is motivated by the fact that…
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…
Traversable Wormholes Supported by Entropy-Inspired Effective Matter Sectors
Jonathan A. Rebouças, Francisco Bento Lustosa, Celio R. Muniz
The thermodynamic interpretation of gravity suggests that modifications of horizon entropy can be encoded in effective geometries and matter distributions. Motivated by the entropy…
Field Sources for Dark Matter Black Holes
G. Alencar, C. R. Muniz, Francisco Tello-Ortiz
We investigate the field-theoretic realization of regular black holes sourced by dark matter halo profiles within nonlinear electrodynamics (NED) minimally coupled to gravity. Star…
Traversable double-throat wormholes in a string cloud background
Yvens Amaral, M. S. Cunha, C. R. Muniz +1
This work constructs a new class of traversable wormhole solutions with a double-throat topology, modeled as a localized perturbation of the Ellis-Bronnikov metric in a string clou…
New Improved Schwarzschild Black Hole and Its Thermodynamics and Topological Classification
G. Alencar, T. M. Crispim, C. R. Muniz +1
We construct a renormalization-group improved Schwarzschild-like black hole geometry using the exact new scheme running for the Newton coupling. The scale identification is impleme…
