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…

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…
