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…
Three-Dimensional Hairy Black Holes in Teleparallel Gravity
P. A. González, Joel Saavedra, Yerko Vásquez
We consider three-dimensional gravity based on torsion. Specifically, we consider an extension of the so-called Teleparallel Equivalent of General Relativity in the presence of a s…
Some cosmological models coming from gravitational theories having torsional degrees of freedom
J. Lorca Espiro, Yerko Vásquez
In this work we consider gravitational theories in which the effect of coupling characteristic classes, appropriately introduced as operators in the Einstein-Hilbert action, has be…
Extremal Hairy Black Holes
P. A. Gonzalez, Eleftherios Papantonopoulos, Joel Saavedra +1
We consider a gravitating system consisting of a scalar field minimally coupled to gravity with a self-interacting potential and an U(1) electromagnetic field. Solving the coupled…
Scalar field perturbations of a Lifshitz black hole in conformal gravity in three dimensions
Marcela Catalan, Yerko Vasquez
We study the reflection and transmission coefficients and the absorption cross section for scalar fields in the background of a Lifshitz black hole in three-dimensional conformal g…
Dirac quasinormal modes of two-dimensional charged Dilatonic Black Holes
Ramon Becar, P. A. Gonzalez, Y. Vasquez
We study charged fermionic perturbations in the background of two-dimensional charged Dilatonic black holes, and we present the exact Dirac quasinormal modes. Also, we study the st…
Dirac Quasinormal Modes of New Type Black Holes in New Massive Gravity
P. A. Gonzalez, Yerko Vasquez
We study new type black holes in three-dimensional New Massive Gravity and we calculate analytically the quasinormal modes for fermionic perturbations for some special cases. Then,…
Fermionic greybody factors of two and five-dimensional dilatonic black holes
Ramón Becar, P. A. González, Yerko Vásquez
We study fermionic perturbations in the background of a two and five-dimensional dilatonic black holes. Then, we compute the reflection and transmission coefficients and the absorp…
Quasinormal modes and greybody factors of a four-dimensional Lifshitz black hole with z=0
Marcela Catalan, Eduardo Cisternas, P. A. Gonzalez +1
We study scalar perturbations for a four-dimensional asymptotically Lifshitz black hole in conformal gravity with dynamical exponent z=0, and spherical topology for the transverse…
