Titolo: What Next in low-energy neutrino cosmology and high-energy neutrino astronomy

Abstract: Neutrino physics is going through a very exciting era. On the low-energy front, experimental anomalies suggest the existence of extra neutrino families, the sterile neutrinos. Such particles could also explain recent cosmological findings of  additional radiation beyond three active neutrinos and photons. On the high-energy front, the IceCube collaboration has detected the first ultra-high energy neutrinos from the cosmos. Such finding has been greeted with a great deal of excitement and raised the question where these particles are coming from. I'll review current cosmological constraints on sterile neutrinos at the light of the most recent data released by the Planck collaboration and discuss on the possible origin of the high-energy IceCube neutrinos as well as perspectives on the new-born era of neutrino astronomy.
