Bounded Electromagnetic Power Flux at Naked Kasner Singularities
Franco Fiorini, P. A. González, Yerko Vásquez
In some occasions, it would appear that classical electromagnetic fields could be able to coexist with strong curvature, naked singularities, in the sense that the electromagnetic…
Reference Frames and Black Hole Thermodynamics
Franco Fiorini, P. A. González, Yerko Vásquez
In the context of the absolute parallelism formulation of General Relativity, and because of the fact that the scalar curvature can be written in purely torsional terms, it was kno…
Timelike geodesics for five-dimensional Schwarzschild and Reissner-Nordström Anti-de Sitter black holes
P. A. González, Marco Olivares, Yerko Vásquez +1
The timelike structure of the five-dimensional Schwarzschild and Reissner-Nordström Anti-de Sitter black holes is studied in detail. Different kinds of motion are allowed and studi…
Massive scalar field perturbations in Weyl black holes
Ramón Bécar, P. A. González, Felipe Moncada +1
In this work we consider the propagation of massive scalar fields in the background of Weyl black holes and we mainly study the effect of the scalar field mass in the spectrum of t…
Charged scalar field perturbations in Ernst black holes
Ramón Bécar, P. A. González, Yerko Vásquez
We consider the propagation of a charged massive scalar field in the background of a four-dimensional Ernst black hole and study its stability analyzing the quasinormal modes (QNMs…
