Unification of a bounce with a viable dark energy era in Gauss-Bonnet gravity

In this work we demonstrate that it is possible to describe a primordial bounce with the dark energy era in a unified way, in the context of Gauss-Bonnet modified gravity. In particular, the early-time bounce has a nearly scale-invariant power spectrum of primordial scalar curvature perturbations, w...
