  • Alfven modes driven nonlinearly by metric perturbations in Anisotropic Magnetized Cosmologies 
    Kuiroukidis, Apostolos; Kleidis, Kostas; Papadopoulos, Demetrios B. (2007)
    We consider anisotropic magnetized cosmologies filled with conductive plasma fluid and study the implications of metric perturbations that propagate parallel to the ambient magnetic field. It is known that in the first-order ...
  • Charged cosmic strings interacting with gravitational and electromagnetic waves 
    Kleidis, Kostas; Kuiroukidis, Apostolos; Nerantzi, Polixeni; Papadopoulos, Demetrios B. (2010-01)
    Under a particular choice of the Ernst potential, we solve analytically the Einstein–Maxwell equations to derive a new exact solution depending on five parameters: the mass, the angular-momentum (per unit mass), α, the ...
  • Gravitomagnetic instabilities in anisotropically expanding fluids 
    Kleidis, Kostas; Kuiroukidis, Apostolos; Papadopoulos, Demetrios B.; Vlahos, Loukas (2008)
    Gravitational instabilities in a magnetized Friedman–Robertson–Walker (FRW) universe, in which the magnetic field was assumed to be too weak to destroy the isotropy of the model, are known and have been studied in the past. ...
  • Graviton production in the scaling of a long-cosmic-string network 
    Kleidis, Kostas; Kuiroukidis, Apostolos; Papadopoulos, Demetrios B.; Verdaguer, Enric (2011-09-15)
    In a previous paper [K. Kleidis, D. B. Papadopoulos, E. Verdaguer, and L. Vlahos, Phys. Rev. D 78, 024027 (2008).] we considered the possibility that (within the early-radiation epoch) there has been (also) a short period ...
