Cosmology

Cosmology is the study of the large scale structure of the Universe, as well as its dynamics. Our group has been involved in the study and development of cosmological models, in particular to explain the accelerated phases of the cosmological evolution, dubbed inflationary phases.

In this seminar, we study and present constraints for two cosmological models based on non-metric theories of gravity, referred to as f(Q) gravity, using both current datasets and forecast Standard Siren events.
The first model is the most general f(Q) model that replicates a ΛCDM background, with deviatio
