Spinning particle orbits around a black hole in an expanding background
I. Antoniou, D. Papadopoulos, L. Perivolaropoulos
We investigate analytically and numerically the orbits of spinning particles around black holes in the post Newtonian limit and in the presence of cosmic expansion. We show that or…
Generating Solutions to the Einstein Field Equations
I. G. Contopoulos, F. P. Esposito, K. Kleidis +2
Exact solutions to the Einstein field equations may be generated from already existing ones (seed solutions), that admit at least one Killing vector. In this framework, a space of…
Imprints of cosmic strings on the cosmological gravitational wave background
Kostas Kleidis, Demetros B Papadopoulos, Enric Verdaguer +1
The equation which governs the temporal evolution of a gravitational wave (GW) in curved space-time can be treated as the Schrodinger equation for a particle moving in the presence…
Dynamo effects in magnetized ideal-plasma cosmologies
K. Kleidis, A. Kuiroukidis, D. B. Papadopoulos +1
The excitation of cosmological perturbations in an anisotropic cosmological model and in the presence of a homogeneous magnetic field has been studied, using the ideal magnetohydro…
Alfven modes driven non-linearly by metric perturbations in anisotropic magnetized cosmologies
A Kuiroukidis, K Kleidis, D B Papadopoulos
We consider anisotropic magnetized cosmologies filled with conductive plasma fluid and study the implications of metric perturbations that propagate parallel to the ambient magneti…
Excitation of MHD waves in magnetized anisotropic cosmologies
A Kuiroukidis, K Kleidis, D B Papadopoulos +1
The excitation of cosmological perturbations in an anisotropic cosmological model and in the presence of a homogeneous magnetic field was studied, using the resistive magnetohydrod…
