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…
Regular Black Strings and Black Hole in Unimodular Gravity Supported by Maxwell Fields
G. Alencar, V. H. U. Borralho
In this work, we obtain regular solutions with a dynamical cosmological function in unimodular gravity. This alternative theory to General Relativity imposes an additional conditio…
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…
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…
