Abstract Models where dark matter and dark energy interact with each other have been
proposed to solve the coincidence problem. We review the motivations underlying the need …

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 …

Abstract Euclid is a European Space Agency medium-class mission selected for launch in
2020 within the cosmic vision 2015–2025 program. The main goal of Euclid is to understand …

Over the past decade, f (R) theories have been extensively studied as one of the simplest
modifications to General Relativity. In this article we review various applications of f (R) …

Dark energy, the mysterious cause of the accelerating expansion of the universe, is one of
the most important fields of research in astrophysics and cosmology today. Introducing the …

Abstract Euclid is a European Space Agency medium-class mission selected for launch in
2019 within the Cosmic Vision 2015–2025 program. The main goal of Euclid is to …

We construct an updated extended compilation of distinct (but possibly correlated) f σ 8 (z)
redshift space distortion (RSD) data published between 2006 and 2018. It consists of 63 …

We construct an updated and extended compilation of growth-rate data based on recent
redshift-space distortion measurements. The data set consists of 34 data points and includes …

We review the recent progress for modified gravity models of dark energy–including f (R)
gravity, scalar-tensor theories, and braneworld models. In f (R) gravity, where the …

In the context of f (R, T) theories of gravity, we study the evolution of scalar cosmological
perturbations in the metric formalism. According to restrictions on the background evolution …
