DESCRIPTION:Prof. Francis Halzen\, Wisconsin IceCube Particle Astrophysics
  Center and Department of Physics\, University of Wisconsin–Madison\nBio
 : I am a theoretician studying problems at the interface of particle physi
 cs\, astrophysics and cosmology. Since 1987\, I have been working on the A
 MANDA experiment\, a first-generation neutrino telescope at the South Pole
 . AMANDA observations represent a proof of concept for IceCube\, a kilomet
 er-scale observatory recently completed.\nThe IceCube project has transfor
 med a cubic kilometer of natural Antarctic ice into a neutrino detector. T
 he 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 cos
 mic neutrinos. The large cosmic neutrino flux observed implies that a sign
 ificant fraction of the energy in the nonthermal universe\, powered by the
  gravitational energy associated with compact objects from neutron stars t
 o supermassive black holes\, is generated by accelerating protons and not 
 just electrons.\n\nI will discuss the instrument\, the analysis of the dat
 a\, and the significance of the discovery of cosmic neutrinos.
