Dymnikova Black Holes in Unimodular Gravity: Maxwell Sources and Vacuum Contributions
G. Alencar, V. H. U. Borralho
In this work, we investigate the Dymnikova regular black hole within the framework of unimodular gravity, emphasizing the role of the effective vacuum sector in the regularization…

Cylindrically Symmetric Black Holes Sourced by Dekel-Zhao Dark Matter
G. Alencar, V. H. U. Borralho, M. S. Cunha +1
In this work, we obtain analytical solutions for a -dimensional black string and a -dimensional black hole, both sourced by the Dekel-Zhao dark matter (DM) density pr…

Regular Black Strings and BTZ Black Hole in Unimodular Gravity Supported by Maxwell Fields
G. Alencar, V. H. U. Borralho
In this work, we obtain a Maxwell source for regular black string and BTZ black hole using the framework of unimodular gravity. This type of alternative to general relativity impos…
