Dymnikova Black Hole Tidal Forces

M. H. Macêdo, A. A. M. Silva, R. R. Landim

In this work we investigate the tidal properties of the Dymnikova regular black hole and their ef fects on massive particles in radial free-fall. Starting from Dymnikova static, sp…

Topological Thermodynamics of Generalized Bardeen Black Hole

A. A. M. Silva, M. H. Macedo, R. R. Landim

Neves and Saa introduced a two parameter spacetime that includes the Hayward, Bardeen, and Simpson-Visser geometries as particular cases. In this work, we employ the generalized of…

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…

Tidal forces around the Letelier-Alencar cloud of strings black hole

Marcos V. de S. Silva, T. M. Crispim, R. R. Landim +2

In this work, we investigate relativistic tidal forces around a black hole sourced by a cloud of strings, described by the generalized Letelier-Alencar solution. We first review th…

Topological Thermodynamics of Black Holes: Revisiting the methods of winding numbers calculation

A. A. M. Silva, G. Alencar, C. R. Muniz +2

In this paper, the equivalence between two methods for computing winding numbers is established: the approach of -mapping topological current and the residue method. The methods…

Dymnikova Black Hole Surrounded by Quintessence

M. H. Macêdo, J. Furtado, R. R. Landim

The Dymnikova black hole (BH) is a regular solution that interpolates between a de Sitter core near the origin and a Schwarzschild-like behavior at large distances. In this work, w…
