We systematically review some standard issues and also the latest developments of
modified gravity in cosmology, emphasizing on inflation, bouncing cosmology and late-time …

Cosmography can be considered as a sort of a model-independent approach to tackle the
dark energy/modified gravity problem. In this review, the success and the shortcomings of …

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 …

We propose an extension of the symmetric teleparallel gravity, in which the gravitational
action L is given by an arbitrary function f of the non-metricity Q and of the trace of the matter …

Abstract The Nobel Prize winning confirmation in 1998 of the accelerated expansion of our
Universe put into sharp focus the need of a consistent theoretical model to explain the origin …

The understanding of stellar structure represents the crossroads of our theories of the
nuclear force and the gravitational interaction under the most extreme conditions observably …

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 consider a gravitational theory in which matter is nonminimally coupled to geometry, with
the effective Lagrangian of the gravitational field being given by an arbitrary function of the …

We discuss the presence of ghostly instabilities for metric-affine theories constructed with
higher order curvature terms. We mainly focus on theories containing only the Ricci tensor …
