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…
Dynamics of f(R)-cosmologies containing Einstein static models
Naureen Goheer, Rituparno Goswami, Peter K. S. Dunsby
We study the dynamics of homogeneous isotropic FRW cosmologies with positive spatial curvature in -gravity, paying special attention to the existence of Einstein static model…
A detailed analysis of structure growth in theories of gravity
Kishore N. Ananda, Sante Carloni, Peter K. S. Dunsby
We investigate the connection between dark energy and fourth order gravity by analyzing the behavior of scalar perturbations around a Friedmann-Robertson-Walker background. The evo…
The Existence of Einstein Static Universes and their Stability in Fourth order Theories of Gravity
Rituparno Goswami, Naureen Goheer, Peter K. S. Dunsby
We investigate whether or not an Einstein Static universe is a solution to the cosmological equations in gravity. It is found that only one class of theories admits a…
