Colloquium: Dr. Marcos Santander, University of Alabama

ABSTRACT: IceCube is a cubic-kilometer neutrino detector deployed in the deep Antarctic ice at the geographic South Pole. In 2013 IceCube reported the first detection of a cosmic flux of high energy neutrinos in the TeV to PeV range. These neutrinos may help us understand some of the most energetic phenomena in the universe, from the acceleration of cosmic rays to the properties of massive compact objects and their environments. This talk will introduce the instrument, present a summary of recent IceCube highlights, and discuss the implications of these results for high-energy astrophysics, in particular for the study of gamma-ray sources.
