N-body methods for relativistic cosmology

, 2014
. We present a framework for general relativistic N-body simulations in the regime of weak gravitational fields. In this approach, Einstein’s equations are expanded in terms of metric perturbations about a Friedmann-Lemâıtre background, which are ...

Non-singular cosmology in a model of non-relativistic gravity

, 2009
We present a model of non-relativistic gravitational theory which is power-counting renormalizable in 3+1 dimensional spacetime. When applied to cosmology, the relativity-violation terms lead to a dark radiation component, which can give rise to a bounce
