SUMMARY:

The ΛCDM model, also known as the concordance model of Cosmology , is the
best to describe the different phases of evolution of the universe and agrees with most
observational data. However, in recent years, several problems have emerged that have
challenged this model. In order to explain some of these problems, many alternative models
have been proposed, such as the addition of new dynamic fluids modeled by different fields,
modifications of Einstein’s general relativity and deeper modifications to standard physics,
such as the possibility of varying fundamental constants. In this thesis, using the most
recent observational data, we test possible deviations from the theory of general relativity,
as well as possible temporal variations in the speed of light. As results, we did not obtain
departures from the standard physics, however, more restrictive constraints should be
performed in the future with better observational data.
