Dirac quasinormal modes for a 4-dimensional Lifshitz Black Hole
Marcela Catalan, Eduardo Cisternas, P. A. Gonzalez +1
We study the quasinormal modes of fermionic perturbations for an asymptotically Lifshitz black hole in 4-dimensions with dynamical exponent z=2 and plane topology for the transvers…
About the coordinate time for photons in Lifshitz Space-times
J. R. Villanueva, Yerko Vásquez
In this paper we studied the behavior of radial photons from the point of view of the coordinate time in (asymptotically) Lifshitz space-times, and we found a generalization to the…
Four-Dimensional Asymptotically AdS Black Holes with Scalar Hair
P. A. Gonzalez, Eleftherios Papantonopoulos, Joel Saavedra +1
We present a new family of asymptotically AdS four-dimensional black hole solutions with scalar hair of a gravitating system consisting of a scalar field minimally coupled to gravi…
Dirac quasinormal modes of Chern-Simons and BTZ black holes with torsion
Ramon Becar, P. A. Gonzalez, Y. Vasquez
We study Chern-Simons black holes in d-dimensions and we calculate analytically the quasinormal modes of fermionic perturbations. Also, we consider as background the five-dimension…
Motion of particles on a Lifshitz black hole in 3+1 dimensions
Marco Olivares, Yerko Vásquez, J. R. Villanueva +1
We study the geodesic structure of a Lifshitz black hole in 3+1 spacetime dimensions that is an exact solution to the Einstein-scalar-Maxwell theory. We investigate the motio…
Particles motion on topological Lifshitz black holes in 3+1 dimensions
Marco Olivares, Germán Rojas, Yerko Vásquez +1
In the present paper we study the causal structure of a topological black hole presented by Mann R. B. JHEP 06, 075 (2009) by mean the standard Lagrangian procedure, which allow us…
Compact extra dimensions in cosmologies with f(T) structure
Franco Fiorini, P. A. Gonzalez, Yerko Vasquez
The presence of compact extra dimensions in cosmological scenarios in the context of f(T)-like gravities is discussed. For the case of toroidal compactifications, the analysis is p…
