Accelerating the Universe with Gravitational Waves
I. A. Brown, L. Schrempp, K. Ananda
Inflation generically produces primordial gravitational waves with a red spectral tilt. In this paper we calculate the backreaction produced by these gravitational waves on the exp…
The influence of structure formation on the cosmic expansion
Chris Clarkson, Kishore Ananda, Julien Larena
We investigate the effect that the average backreaction of structure formation has on the dynamics of the cosmological expansion, within the concordance model. Our approach in the…
On the co-existence of matter dominated and accelerating solutions in f(G)-gravity
Naureen Goheer, Rituparno Goswami, Peter K. S. Dunsby +1
Working within the theory of modified Gauss-Bonnet gravity, we show that FLRW--like power--law solutions only exist for a very special class of f(G)theories. Furthermore, we point…
