Gravitational waves in an expanding Universe
We study the tensorial modes of the two-fluid model, where one of this fluids has an equation of state p = −ρ/3 (variable cosmological constant, cosmic string fluid, texture) or p = −ρ (cosmological constant), while the other fluid is an ordinary matter (radiation, stiff matter, incoherent matter). In the first case, it is possible to have a closed Universe whose dynamics can be that of an open...
متن کاملNonlinear Gravitational Clustering in Expanding Universe
The gravitational clustering of collisionless particles in an expanding universe is modelled using some simple physical ideas. I show that it is possible to understand the nonlinear clustering in terms of three well defined regimes: (1) linear regime; (2) quasilinear regime which is dominated by scale-invariant radial infall and (3) nonlinear regime dominated by nonradial motions and mergers. M...
متن کاملPlasma waves driven by gravitational waves in an expanding universe
In a Friedmann-Robertson-Walker (FRW) cosmological model with zero spatial curvature, we consider the interaction of the gravitational waves with the plasma in the presence of a weak magnetic field. Using the relativistic hydromagnetic equations it is verified that large amplitude magnetosonic waves are excited, assuming that both, the gravitational field and the weak magnetic field do not brea...

The gravitational clustering of collisionless particles in an expanding universe is modelled using some simple physical ideas.

متن کاملExpanding impulsive gravitational waves
We explicitly demonstrate that the known solutions for expanding impulsive spherical gravitational waves that have been obtained by a “cut and paste” method may be considered to be impulsive limits of the Robinson–Trautman vacuum type N solutions. We extend these results to all the generically distinct subclasses of these solutions in Minkowski, de Sitter and anti-de Sitter backgrounds. For the...
