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…
Power-law cosmic expansion in f(R) gravity models
Naureen Goheer, Julien Larena, Peter K. S. Dunsby
We show that within the class of f(R) gravity theories, FLRW power-law perfect fluid solutions only exist for R^n gravity. This significantly restricts the set of exact cosmologica…
Spatially averaged cosmology in an arbitrary coordinate system
J. Larena
This paper presents a general averaging procedure for a set of observers which are tilted with respect to the cosmological matter fluid. After giving the full set of equations desc…
Reinterpreting quintessential dark energy through averaged inhomogeneous cosmologies
Julien Larena, Thomas Buchert, Jean-Michel Alimi
Regionally averaged relativistic cosmologies have recently been considered as a possible explanation for the apparent late time acceleration of the Universe. This contribution repo…
