Constraining neutrino physics with observations of the cosmic microwave background
  OKC colloquia

Tuesday 31 January 2017
from 13:15 to 14:30
at FB42
Speaker : Massimiliano Lattanzi (Università di Ferrara)
Abstract : Cosmological observations represent a powerful tool to constrain neutrino physics, complementary to laboratory experiments. In particular, observations of the cosmic microwave background (CMB) have the potential to constrain the properties of relic neutrinos, as well as of additional light relic particles in the Universe. The data released by the Planck collaboration in 2015 provide the most precise measurements to date of the temperature and polarisation anisotropies of the CMB. I will present current constraints on neutrino properties, including their mass and effective number, from the most recent Planck data, possibly in combination with other cosmological probes, especially galaxy surveys. I will also discuss prospects from future experiments, both from the ground and from space. (Host: Sunny Vagnozzi)
