Massive Scalar Field Perturbations of Black Holes Immersed in Chaplygin-Like Dark Fluid
Ramón Bécar, P. A. González, Eleftherios Papantonopoulos +1
We consider massive scalar field perturbations in the background of black holes immersed in Chaplygin-like dark fluid (CDF), and we analyze the photon sphere modes, the de Sitter m…
Phase transitions in four-dimensional AdS black holes with a nonlinear electrodynamics source
Ramon Becar, P. A. Gonzalez, Joel Saavedra +2
In this work we consider black hole solutions to Einstein theory coupled to a nonlinear power-law electromagnetic field with a fixed exponent value. We study the extended phase spa…
Particle collisions near a three-dimensional warped AdS black hole
Ramón Bécar, P. A. González, Yerko Vásquez
In this paper we consider the warped AdS black hole solution of topologically massive gravity with a negative cosmological constant, and we investigate the possibility that i…
Quasinormal modes of Four Dimensional Topological Nonlinear Charged Lifshitz Black Holes
Ramon Becar, P. A. Gonzalez, Yerko Vasquez
We study scalar perturbations of four dimensional topological nonlinear charged Lifshitz black holes with spherical and plane transverse sections, and we find numerically the quasi…
Quasinormal modes of non-Abelian hyperscaling violating Lifshitz black holes
Ramón Bécar, P. A. González, Yerko Vásquez
We study the quasinormal modes of scalar field perturbations in the background of non-Abelian hyperscaling violating Lifshitz black holes. We find that the quasinormal frequencies…
Greybody Factors of Massive Charged Fermionic Fields in a Charged Two-Dimensional Dilatonic Black Hole
Ramon Becar, P. A. Gonzalez, Joel Saavedra +1
We study massive charged fermionic perturbations in the background of a charged two-dimensional dilatonic black hole, and we solve the Dirac equation analytically. Then, we compute…
