ICECUBE: Opening a Neutrino Window on the Universe from the South Pole

McNamara Alumni Center at 7:00 pm

Abstract:  The IceCube project at the South Pole melted 86 holes 2.5 kilometer deep in the Antarctic icecap to construct an enormous astronomical observatory. The experiment discovered a flux of neutrinos from deep space with energies more than a million times those of neutrinos produced at accelerator laboratories. These cosmic neutrinos are created in some of the most violent processes in the universe since the Big Bang and originate in the cosmic particle accelerators that are still enigmatic sources of cosmic rays. This lecture will discuss the IceCube neutrino telescope and the discovery of high-energy neutrinos of cosmic origin. It will highlight the recent discovery that high-energy neutrinos—and cosmic rays—originate in sources powered by rotating supermassive black holes.
