A number of challenges to the standard Λ CDM model have been emerging during the past
few years as the accuracy of cosmological observations improves. In this review we discuss …

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 constrain six possible extensions to the Λ cold dark matter (CDM) model using
measurements from the Dark Energy Survey's first three years of observations, alone and in …

We study observational constraints on the nonmetricity f (Q)-gravity which reproduces an
exact Λ CDM background expansion history while modifying the evolution of linear …

Despite its continued observational successes, there is a persistent (and growing) interest in
extending cosmology beyond the standard model, Λ CDM. This is motivated by a range of …

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 …

The discovery of cosmic acceleration has triggered a consistent body of theoretical work
aimed at modeling its phenomenology and understanding its fundamental physical nature …

We investigate the evolution of linear perturbations in the Symmetric Teleparallel Gravity,
namely f (Q) gravity, for which we design the f (Q) function to match specific expansion …

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 …

Long range scalar fields with a coupling to matter appear to violate known bounds on
gravitation in the solar system and the laboratory. This is evaded thanks to screening …
