Abstract The standard Λ Cold Dark Matter (ΛCDM) cosmological model provides a good
description of a wide range of astrophysical and cosmological data. However, there are a …

We provide further evidence that a massless cosmological scalar field with a nonminimal
coupling to the Ricci curvature of the type M pl 2 (1+ ξ σ n/M pl n) alleviates the existing …

We use Planck 2018 data to constrain the simplest models of scalar-tensor theories
characterized by a coupling to the Ricci scalar of the type F (σ) R with F (σ)= N pl 2+ ξ σ 2 …

We study three different extended scalar-tensor theories of gravity by also allowing a
negative sign for the kinetic term for the scalar field in the Jordan frame. Our scope is to …

We study the cosmological constraints on the variation of Newton's constant and on post-
Newtonian parameters for simple models of the scalar-tensor theory of gravity beyond the …

We study the cosmological effects of a Galileon term in scalar-tensor theories of gravity. The
subset of scalar-tensor theories considered are characterized by a nonminimal coupling F …

We study the variation of the gravitational constant on cosmological scales in scalar-tensor
theories of gravity. We focus on the simplest models of scalar-tensor theories with a coupling …

Abstract The extended Jordan-Brans-Dicke (eJBD) theory of gravity is constrained by a host
of astrophysical and cosmological observations spanning a wide range of scales. The …

Modified gravity is one of the best frameworks that can alleviate cosmological tensions, due
to the huge freedom one has to construct models. Gravitational modifications affect the late …

Inflation is naturally a very expansive topic, and we summarize here exclusively the main
aspects relevant for this manuscript. Parts of the theory described in this section has also …
