Abstract

Future cosmological measurements should enable the sum of neutrino masses to be determined indirectly through their effects on the expansion rate of the Universe and the clustering of matter. I will discuss the cosmological effects of neutrinos and how they appear in CMB and large-scale structure observables. I will outline how the mass measurement may be reached, step-wise, using data collected during the coming decade. Finally, I will explore the dependence of the mass constraint on experimental details and examine degeneracies with other cosmological parameters.
