On the Cosmological Constraints on Neutrino Masses

The confirmation of nonzero neutrino masses marked the first departure from the Standard Model of particle physics. Nonetheless, the neutrino mass sector still contains unknown quantities and exhibits tensions among different measurements. In this seminar, I will address the emerging anomaly between cosmological and oscillation constraints on the sum of neutrino masses. I will review the main implications of neutrino masses at both the background and perturbations levels, discussing the primary neutrino effects to which CMB data is sensitive, and finding valuable hints to evade cosmological bounds.
