  Recent advances in cosmic observations have brought us to the verge of
discovery of the absolute scale of neutrino masses. Nonzero neutrino masses are
known evidence of new physics beyond the Standard Model. Our understanding of
the clustering of matter in the presence of massive neutrinos has significantly
improved over the past decade, yielding cosmological constraints that are
tighter than any laboratory experiment, and which will improve significantly
over the next decade, resulting in a guaranteed detection of the absolute
neutrino mass scale.
