Description
In this talk, 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. Our findings show that the CMB neutrino-mass bound is mostly a background measurement, i.e., how the neutrino energy density evolves with time.
