Abstract:
The IceCube project at the South Pole melted 86 holes 2.5 kilometer deep in th e Antarctic icecap to construct an enormous astronomical observatory. The experiment discovered a flux of neutrinos from deep space with energies mo re than a million times those of neutrinos produced at accelerator laborat ories.

These cosmic neutrinos are created in some of the most vi olent processes in the universe since the Big Bang and originate in the co smic particle accelerators that are still enigmatic sources of cosmic rays . This lecture will discuss the IceCube neutrino telescope and the discove ry of high-energy neutrinos of cosmic origin.

It will highlight the recent discovery that high-energy neutrinos—and cosmic rays—origin ate in sources powered by rotating supermassive black holes.
