Quasinormal modes for a non-minimally coupled scalar field in a five-dimensional Einstein-power-Maxwell background
Angel Rincon, P. A. Gonzalez, Grigoris Panotopoulos +2
We study the propagation of massless scalar fields non-minimally coupled to gravity in the background of five-dimensional Einstein-power-Maxwell black holes, and using the WKB and…
Slowly rotating dark energy stars
Grigoris Panotopoulos, Ángel Rincón, Ilídio Lopes
We study isotropic and slowly-rotating stars made of dark energy adopting the extended Chaplygin equation-of-state. We compute the moment of inertia as a function of the mass of th…
Accretion of matter and spectra of Binary X-ray sources in Massive Gravity
Grigoris Panotopoulos, Angel Rincon, Ilídio Lopes
We study low-mass binary X-ray sources involving stellar mass black holes within massive gravity. Regarding the accretion disk, we adopt the standard model for an optically thick,…
ISCOs and OSCOs in the presence of a positive cosmological constant in massive gravity
Angel Rincon, Grigoris Panotopoulos, Ilidio Lopes +1
We study the impact of a non-vanishing (positive) cosmological constant on the innermost and outermost stable circular orbits (ISCOs and OSCOs, respectively) within massive gravity…
Superradiant instability and charged scalar quasinormal modes for -dimensional Coulomb-like AdS black holes from nonlinear electrodynamics
P. A. González, Ángel Rincón, Joel Saavedra +1
We study the propagation of charged scalar fields in the background of -dimensional Coulomb-like AdS black holes, and we show that such propagation is unstable under Dirichlet…
Growth of structures and redshift-space distortion data in scale-dependent gravity
Grigoris Panotopoulos, Ángel Rincón
This study is devoted to the implications of scale-dependent gravity in Cosmology. Redshift-space distortion data indicate that there is a tension between CDM and available obse…
