IceCube is a one-cubic-kilometer international high-energy neutrino observatory built in the South Pole glacier. The detector is based on a three-dimensional array of 5160 optical sensors deployed deep into the polar ice to collect Cherenkov radiation emitted by charged particles traveling through and near the detector.
IceCube will open unexplored bands for astronomy, including the PeV (1015 eV) energy region, where the Universe is opaque to high energy gamma rays originating from beyond the edge of our own galaxy, and where cosmic rays do not carry directional information because of their deflection by magnetic fields. The instrument may, for example, answer the question of whether the fascinating multi-TeV photons originating in the Crab supernova remnant and near the supermassive black holes of active galaxies are of hadronic or electromagnetic origin. IceCube will provide a totally novel viewpoint on the multi-messenger astronomy of gamma ray bursts, which have been identified as a possible source of the highest energy particles in nature.
IceCube also occupies a unique place in the multi-prong attack on the particle nature of dark matter, with unmatched sensitivity to cold dark matter particles approaching TeV masses. As a particle physics experiment with the capability to detect neutrinos with energies far beyond those produced at accelerators, IceCube will join the race to discover supersymmetric particles and the topological defects created in grand unified phase transitions in the early universe. The detection of cosmic neutrino beams would open the opportunity to study neutrino oscillations over Megaparsec baselines.
In Brussels, we focus on the following analyses:
