This report provides an extensive review of the experimental programme of direct detection
searches of particle dark matter. It focuses mostly on European efforts, both current and …

Ultra-light dark matter is a class of dark matter models (DM), where DM is composed by
bosons with masses ranging from 10^-24\, eV< m< eV 10-24 eV< m< eV. These models …

We propose a relativistic gravitational theory leading to modified Newtonian dynamics, a
paradigm that explains the observed universal galactic acceleration scale and related …

Although dark matter is a central element of modern cosmology, the history of how it became
accepted as part of the dominant paradigm is often ignored or condensed into an anecdotal …

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 …

Astronomical observations reveal a major deficiency in our understanding of physics—the
detectable mass is insufficient to explain the observed motions in a huge variety of systems …

After a decade and a half of research motivated by the accelerating universe, theory and
experiment have reached a certain level of maturity. The development of theoretical models …

We investigate the observational consequences of a novel class of stable interacting dark
energy (IDE) models, featuring interactions between dark matter (DM) and dark energy (DE) …

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 …
