Construction and commissioning of the IceCube kilometer cube neutrino detector and its low energy extension DeepCore have been completed. The IceCube project has transformed a cube kilometer of natural Antarctic ice into a particle detector. The instrument detects neutrinos over a wide energy range: from 10 GeV atmospheric neutrinos to 1010 GeV cosmogenic neutrinos. We will discuss initial results based on a subsample of the ~100,000 neutrino events recorded during construction. We will emphasize the first measurement of the high-energy atmospheric neutrino spectrum, the search for the still enigmatic sources of the Galactic and extragalactic cosmic rays and for the particle nature of dark matter.
Coffee and cookies before the presentation at 3:15 pm, and refreshments after the presentation will both be served in Room 128.
