IceCube: The Discovery of Cosmic Neutrinos

12.12.2016 16:00 – 18:00

The IceCube project has transformed a cubic kilometer of natural Antarctic ice into a neutrino detector. The instrument detects more than 100,000 neutrinos per year in the GeV to PeV energy range. Among those, we have isolated a flux of high-energy cosmic neutrinos. I will discuss the instrument, the analysis of the
data, and the significance of the discovery of cosmic neutrinos. The large cosmic neutrino flux observed implies that the Universe’s energy density in high energy neutrinos is the same as that in gamma rays, suggesting that the sources are connected and that a multitude of astronomical objects await discovery.
