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…
Quasinormal modes of regular black holes with non linear-Electrodynamical sources
Grigoris Panotopoulos, Ángel Rincón
We compute the spectrum of quasinormal frequencies of regular black holes obtained in the presence of Non-Linear Electrodynamics. In particular, we perturb the black hole with a mi…
Model comparison using supernovae and Hubble parameter data
Grigoris Panotopoulos, Angel Rincon
We compare several well-known cosmological dark energy models using observational data coming both from type Ia supernovae and from Hubble parameter measurements. First we use supe…
Greybody factors for a minimally coupled massless scalar field in Einstein-Born-Infeld dilaton spacetime
Grigoris Panotopoulos, Angel Rincon
We have analyzed in detail the propagation of a minimally coupled massless scalar field in the gravitational background of a four-dimensional Einstein-Born-Infeld dilaton charged b…
