The path to a neutrino mass sum measurement from cosmology

Abstract:
We know standard model neutrinos have mass from oscillation experiments measuring the difference between mass states, but we do not know the absolute mass scale of neutrinos. Cosmology is in a strong position to resolve this question as massive neutrinos leave a distinct imprint on cosmological observables. I will review the current status of neutrino cosmology and discuss what we can expect to see in the next years.
