Anisotropic Cosmology with Inhomogeneous and Nonlinear -Models
N. Dimakis, A. Giacomini, G. Leon +2
We investigate the cosmological dynamics of the nonlinear -model in a locally rotational symmetric Bianchi V background geometry. We employ the and the $SL(2,\mathbb{R})…
Lyapunov Exponents and Phase Transitions in Four-Dimensional AdS Black Holes with a Nonlinear Electrodynamics Source
Ramón Bécar, P. A. González, Felipe Moncada +1
We investigate the relationship between dynamical instability and thermodynamic phase transitions in four-dimensional Anti--de Sitter black holes in Einstein gravity coupled to a n…
Noncoincidence -Cosmology with Dark Matter Coupled to Gravity
A. Abebe, P. S. Apostolopoulos, A. Giacomini +3
We investigate FLRW cosmology in the framework of symmetric teleparallel gravity with a nonminimal coupling between dark matter and the gravitational field. In the noncoinci…
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…
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…
Quasinormal Modes, Stability Analysis and Absorption Cross Section for 4-dimensional Topological Lifshitz Black Hole
P. A. Gonzalez, Felipe Moncada, Yerko Vasquez
We study scalar perturbations in the background of a Topological Lifshitz black hole in four dimensions. We compute analytically the quasinormal modes and from these modes we show…
