We review recent developments and results in testing general relativity (GR) at cosmological
scales. The subject has witnessed rapid growth during the last two decades with the aim of …

We review the paradigm of holographic dark energy (HDE), which arises from a theoretical
attempt of applying the holographic principle (HP) to the dark energy (DE) problem. Making …

We review recent progress in the construction of modified gravity models as alternatives to
dark energy as well as the development of cosmological tests of gravity. Einstein's theory of …

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 …

We present constraints on extensions of the minimal cosmological models dominated by
dark matter and dark energy, Λ CDM and w CDM, by using a combined analysis of galaxy …

We present a detailed analysis of redshift-space distortions in the two-point correlation
function of the 6dF Galaxy Survey (6dFGS). The K-band selected subsample which we …

We propose a universal description of dark energy and modified gravity that includes all
single-field models. By extending a formalism previously applied to inflation, we consider the …

We present a turnkey solution, ready for implementation in numerical codes, for the study of
linear structure formation in general scalar-tensor models involving a single universally …

We review and extend a novel approach that we recently introduced, to describe general
dark energy or scalar-tensor models. Our approach relies on an Arnowitt-Deser-Misner …

We review one of the most fruitful areas in cosmology today that bridge theory and data—the
temporal growth of large-scale structure. We go over the growth's physical foundations, and …
