Abstract:

Cosmological measurements of the Cosmic Microwave Background radiation, and of the large-scale distribution of galaxies, have taught us a great deal about the origins and content of the universe. In the next decade we anticipate using new microwave background data, and new measurements of the positions, masses and gravitational distortions of galaxies and galaxy clusters, to measure the total mass of the neutrino particles. I will discuss our path to making this indirect detection of the absolute neutrino mass scale using cosmological data, which will complement direct measurements. This will progress from using current data, including the Planck satellite, to new measurements coming from Chile from the early 2020s with the Simons Observatory and the Large Synoptic Survey Telescope.
