IceCube neutrino observatory at the South Pole: recent results

The IceCube neutrino observatory, the largest particle detector in the world (1 km3 ), is currently being built at the South Pole. IceCube looks down through the Earth to filter out lower-energy particles and uses optical sensors embedded deep in the ultra-clean Antarctic ice to detect high energy neutrinos via Cherenkov radiation from charged particles produced in neutrino interactions. A summary of selected recent results is presented.
