In this review we present a thoroughly comprehensive survey of recent work on modified
theories of gravity and their cosmological consequences. Amongst other things, we cover …

Massive gravity has seen a resurgence of interest due to recent progress which has
overcome its traditional problems, yielding an avenue for addressing important open …

We introduce the Vainshtein mechanism which plays a crucial role in massive gravities, as
well as in related theories such as Galileons and their extensions. This mechanism, also …

The cosmological equations suggested by the non-relativistic renormalizable gravitational
theory proposed by Hořava are considered. It is pointed out that the early universe …

We argue that the cosmological constant problem can be solved in a braneworld model with
infinite-volume extra dimensions, avoiding no-go arguments applicable to theories that are …

We systematically explore the spectrum of gravitational perturbations in codimension-1 DGP
braneworlds, and find a 4D ghost on the self-accelerating branch of solutions. The ghost …

The self-accelerating universe realizes the accelerated expansion of the universe at late
times by large-distance modification of general relativity (GR) without a cosmological …

We review various aspects of de Sitter spacetime in string theory: its status as an Effective
Field Theory spacetime solution, its relation to the vacuum energy problem in string theory …

This is a review of aspects of D‐brane applications to particle physics and cosmology. D‐
branes provide interesting alternatives to standard unification of interactions. Moreover they …
