Fredagskollokvium: Neutrino physics from precision cosmology
Steen Hannestad, Department of Physics and Astronomy, Aarhus University.
Over the last decade precision measurements of the cosmic microwave background and the large scale distribution of galaxies have made it possible to use cosmology to probe many aspects of particle physics. Perhaps the prime example is neutrino physics. For example, because neutrinos have a profound impact on how structures form in the Universe, cosmological observations can be used to probe the neutrino mass with high precision. In the talk I will review the status of cosmology as a tool for probing the physics of neutrinos and other weakly interacting particles. I will also outline the future of the field, with particular focus on upcoming projects such as EUCLID and LSST.
