Evanescent gravitons in Warped Anti-de Sitter space
Gaston Giribet, Yerko Vasquez
Besides black holes, the phase space of three-dimensional massive gravity about Warped-Anti de Sitter (WAdS) space contains solutions that decay exponentially in time. They describ…
Bounded orbits for photons as a consequence of extra dimensions
P. A. Gonzalez, Marco Olivares, Yerko Vasquez
In this work, we study the geodesic structure for a geometry described by a spherically symmetric four-dimensional solution embedded in a five-dimensional space known as a brane-ba…
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…
Scalar Perturbations of Nonlinear Charged Lifshitz Black Branes with Hyperscaling Violation
P. A. González, Yerko Vásquez
We study scalar perturbations of nonlinear charged Lifshitz black branes with hyperscaling violating factor, and we find numerically the quasinormal modes for scalar fields. Then,…
Teleparallel Equivalent of Lovelock Gravity
P. A. Gonzalez, Yerko Vasquez
There is a growing interest in modified gravity theories based on torsion, as these theories exhibit interesting cosmological implications. In this work, inspired by the teleparall…
Motion of particles on a Four-Dimensional Asymptotically AdS Black Hole with Scalar Hair
P. A. Gonzalez, Marco Olivares, Yerko Vasquez
Motivated by black hole solutions with matter fields outside their horizon, we study the effect of these matter fields in the motion of massless and massive particles. We consider…
