Lagrangian formulation for an extended cosmological equation-of-state
Grigoris Panotopoulos, Ilidio Lopes, Angel Rincon
We show that the extended cosmological equation-of-state developed starting from a Chaplygin equation-of-state, recently applied to stellar modeling, is a viable dark energy model…
Quasinormal spectra of scale-dependent Schwarzschild-de Sitter black holes
Grigoris Panotopoulos, Angel Rincon
We compute the quasinormal spectra for scalar, Dirac and electromagnetic perturbations of the Schwarzschild-de Sitter geometry in the framework of scale-dependent gravity, which is…
Radial oscillations and tidal Love numbers of dark energy stars
Grigoris Panotopoulos, Angel Rincon, Ilidio Lopes
We investigate the properties of relativistic stars made of dark energy. We model stellar structure assuming i) isotropic perfect fluid and ii) a dark energy inspired equation of s…
Geodesic analysis and black hole shadows on a general non--extremal rotating black hole in five--dimensional gauged supergravity
E. Contreras, Á. Rincón, G. Panotopoulos +1
In this work, motivated by the fact that higher-dimensional theories predict the existence of black holes which differ from their four-dimensional counterpart, we analyse the geode…
Scale-dependent slowly rotating black holes with flat horizon structure
Angel Rincon, Grigoris Panotopoulos
We study slowly rotating four-dimensional black holes with flat horizon structure in scale-dependent gravity. First we obtain the solution, and then we study thermodynamic properti…
Greybody factor and quasinormal modes of Regular Black Holes
Ángel Rincón, Victor Santos
In this work, we investigate the quasinormal frequencies of a class of regular black hole solutions which generalize Bardeen and Hayward spacetimes. In particular, we analyze scala…
