Sumario:General Relativity (GR) has been the most successful theory to describe gravity up to now, since it is in agreement with many different tests. Despite its achievements, GR also presents some problems that have opened the door to explore other theories beyond it in order to address these issues, for example the fact that it predicts the existence of spacetime singularities at high-energy scales or requires the yet non-detected dark energy/matter for the consistency of the cosmological models. Chapter 1 discusses the different ways one can modify GR and, among all of the different proposals, this Thesis is based on the so-called Ricci-Based Gravities (RBG) a subgroup of gravitational theories inside the metric-affine or Palatini formalism (where the connection and the metric are kept as independent entities)...
