The IceCube project has transformed one cubic kilometer of natural Antarctic ice into a neutrino detector. The instrument detects 100,000 neutrinos per year in the GeV to PeV energy range. Among those, we have recently isolated a flux of high-energy cosmic neutrinos. Professor Halzen will discuss the instrument, the analysis of the data, and the significance of the discovery of cosmic neutrinos.
Francis Halzen is Hilldale and Gregory Breit Professor at the University Wisconsin-Madison, WI, USA. He is a theoretician studying problems at the interface of particle physics, astrophysics and cosmology. Since 1987, Professor Halzen has 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 kilometre-scale observatory recently completed.
