Electrically Charged Non-Abelian Black String in Anti-de Sitter Space
G. Alencar, R. N. Costa Filho, I. Jardim +1
We construct a new family of static, electrically charged, cylindrically symmetric black-string solutions of four-dimensional Einstein--Yang--Mills theory with a negative cosmologi…
Colored Black Holes in Logarithmic Nonlinear Yang--Mills Theory
Celio R. Muniz
We construct static, spherically symmetric, and asymptotically flat colored black holes in four-dimensional Einstein gravity coupled to a logarithmic nonlinear Yang--Mills field wi…
Junction Conditions, Radial Stability, Thermodynamics, Optical Geometry and Appearance of Polymer-Quintessence Thin-Shell Wormholes
Jonathan A. Rebouças, Edson Otoniel, M. C. Araújo +2
The authors construct a reflection‑symmetric thin‑shell wormhole from a polymer‑corrected black‑hole metric surrounded by Kiselev‑type quintessence and examine its junction conditi…
Gravitational Lensing in a Kasner Background: Distinguishing Wormholes and Black Holes
Celio R. Muniz, Jonathan A. Rebouças, M. B. Cruz +1
We investigate gravitational lensing by compact objects embedded in anisotropic Bianchi-I cosmologies using directional Jacobi maps within the thin-lens approximation. The formalis…
Regularized Black Hole Solution from a New String Cloud Source
C. R. Muniz, Jonathan Alves Rebouças, Leonardo Tavares de Oliveira +2
We construct a new family of regular black hole solutions supported by the novel Letelier-Alencar string cloud and regularized through a rational Dagum-type distribution. The regul…
Are Padé approximants suitable for modelling shape functions of traversable wormholes?
Jonathan Alves Rebouças, Celio Rodrigues Muniz
This study investigates the applicability of Padé approximants in constructing suitable shape functions for traversable wormholes, emphasizing their ability to satisfy essential g…
