Prof. Francis Halzen, Wisconsin IceCube Particle Astrophysics Center and Department of Physics, University of Wisconsin–Madison Bio: I am a theoretician studying problems at the interface of particle physics, astrophysics and cosmology. Since 1987, I have been working on the AMANDA experiment, a first-generation neutrino telescope at the South Pole. AMANDA observations represent a proof of concept for IceCube, a kilometer-scale observatory recently completed. |

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. The large cosmic neutrino flux observed implies that a significant fraction of the energy in the nonthermal universe, powered by the gravitational energy associated with compact objects from neutron stars to supermassive black holes, is generated by accelerating protons and not just electrons.
I will discuss the instrument, the analysis of the data, and the significance of the discovery of cosmic neutrinos.
