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 …
Extended Theories of Gravity can be considered as a new paradigm to cure shortcomings of General Relativity at infrared and ultraviolet scales. They are an approach that, by …
General Relativity has shown an outstanding observational success in the scales where it has been directly tested. However, modifications have been intensively explored in the …
Over the past decade, f (R) theories have been extensively studied as one of the simplest modifications to General Relativity. In this article we review various applications of f (R) …
Modified gravity theories have received increased attention lately due to combined motivation coming from high-energy physics, cosmology, and astrophysics. Among …

We review the recent literature on modified theories of gravity in the Palatini approach. After discussing the motivations that lead to consider alternatives to Einstein's theory and to treat …
Beyond Einstein's Gravity is a graduate level introduction to extended theories of gravity and cosmology, including variational principles, the weak-field limit, gravitational waves …

In this work, we construct traversable wormhole geometries in the context of f (R) modified theories of gravity. We impose that the matter threading the wormhole satisfies the energy …

Astrophysical observations are pointing out huge amounts of “dark matter” and “dark energy” needed to explain the observed large scale structure and cosmic dynamics. The emerging …
