Colloqui di Fisica Constraining neutrino physics through observations of the cosmic microwave background Massimiliano Lattanzi 10-01-2017 - 15:00 AULA B - Via Della Vasca Navale 84
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 publicly available measurements to date of the temperature and polarization anisotropies of the cosmic microwave background. 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. |
