Event Details

Though observed neutrino oscillations provide robust measures of the neutrino mass differences, it is the cosmic microwave background and cosmological large scale structure that provide the strongest constraints on the absolute neutrino masses. I review how cosmology can do this, and what model dependencies remain in making these constraints. As upcoming cosmological measures’ sensitivities approach the minimal required mass differences from oscillation measures, a critical reexamination of the model dependencies of cosmological neutrino mass constraints is warranted. I will describe our results in testing such dependencies.
