Dynamical systems methods and statefinder diagnostic of interacting vacuum energy models
Grigoris Panotopoulos, Angel Rincon, Nelson Videla +1
We study three interacting dark energy models within the framework of four-dimensional General Relativity and a spatially flat Universe. In particular, we first consider two vacuum…
Quasinormal modes of five-dimensional black holes in non-commutative geometry
Grigoris Panotopoulos, Ángel Rincón
We compute the spectrum of quasinormal frequencies of five-dimensional black holes obtained in noncommutative geometry. In particular, we study scalar perturbations of a massive sc…
Minimal Geometric Deformation in a Reissner-Nordström background
Angel Rincon, Luciano Gabbanelli, Ernesto Contreras +1
This article is devoted to the study of new exact analytical solutions in the background of Reissner-Nordström space-time by using gravitational decoupling via minimal geometric de…
Anisotropic strange quark stars with a non-linear equation-of-state
Ilídio Lopes, Grigoris Panotopoulos, Ángel Rincón
We obtain an exact analytical solution to Einstein's field equations assuming a non-linear equation-of-state and a particular mass function. Our solution describes the interior of…
Relativistic strange quark stars in Lovelock gravity
Grigoris Panotopoulos, Ángel Rincón
We study relativistic non-rotating stars in the framework of Lovelock gravity. In particular, we consider the Gauss-Bonnet term in a five-dimensional spacetime, and we investigate…
Black hole shadow of a rotating scale--dependent black hole
Ernesto Contreras, Ángel Rincón, Grigoris Panotopoulos +2
In this work, starting from a spherically symmetric scale--dependent black hole, a rotating solution is obtained by following the Newman--Janis algorithm without complexification.…
