Abstract(s) :

(Anglais) The IceCube neutrino observatory is currently under construction in the deep ice at the geographic South Pole, reaching 75% completion whilst already taking data. When completed in 2011, it will consist of nearly 5000 digital optical modules on more than 80 strings, capable of detecting the Cherenkov radiation from high-energy neutrino-induced charged leptons. The detection of astrophysical neutrinos can help identify the sources of the high energy cosmic rays since other messengers, such as photons or protons, are absorbed or deflected during propagation. The cubic-kilometer under-ice instrument, complemented by an extensive air- shower array, allows access to neutrino energies up to the PeV range, and to sensitivities below expected neutrino fluxes from some astrophysical sources if they accelerate hadrons. I will summarize current results of IceCube and its predecessor AMANDA, as well as the physics capabilities of the full observatory.
