This paper reviews scalar–tensor theories characterized by a Lagrangian that, despite the
presence of second-order derivatives, contains a single scalar degree of freedom. These …

Gravitational waves (GWs) provide a new tool to probe the nature of dark energy (DE) and
the fundamental properties of gravity. We review the different ways in which GWs can be …

The dawn of the twenty-first century came with very positive prospects for gravity, cosmology,
and astrophysics. Technological progress made it possible for cosmology to enter to its …

The precision of the cosmological data allows us to accurately approximate the predictions
for cosmological observables by Taylor expanding up to a low order the dependence on the …

We explore the role of redshift-space galaxy clustering data in constraining nongravitational
interactions between dark energy (DE) and dark matter (DM), for which state-of-the-art limits …

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

The disagreement between direct late-time measurements of the Hubble constant from the
SH0ES collaboration, and early-universe measurements based on the ΛCDM model from …

An accurate theoretical template for the galaxy power spectrum is key for the success of
ongoing and future spectroscopic surveys. We examine to what extent the effective field …

Abstract We apply the Effective Field Theory of Large-Scale Structure to analyze the wCDM
cosmological model. By using the full shape of the power spectrum and the BAO post …

After calibrating the predictions of the Effective Field Theory of Large-Scale Structure against
several sets of simulations, as well as implementing a new method to assert the scale cut of …
