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…
Unifying the study of background dynamics and perturbations in -gravity
Sante Carloni, Kishore N. Ananda, Peter K. S. Dunsby +1
In this paper we show how the covariant gauge invariant equations for the evolution of scalar, vector and tensor perturbations for a generic -gravity theory can be recast in…
A characteristic signature of fourth order gravity
Kishore N. Ananda, Sante Carloni, Peter K. S. Dunsby
We present for the first time the complete matter power spectrum for gravity which has been derived from the fourth order scalar perturbation equations. This leads to the dis…
Vector modes generated by primordial density fluctuations
Teresa Hui-Ching Lu, Kishore Ananda, Chris Clarkson
While vector modes are usually ignored in cosmology since they are not produced during inflation they are inevitably produced from the interaction of density fluctuations of differ…
