"High Energy Astrophysical Neutrinos"

Speaker: Kara Hoffman (University of Maryland)

In the summer of 2012, the IceCube Neutrino Observatory announced the observation of two neutrino interactions deep in the south polar icecap, each with energies in excess of 1015 eV, making them the highest energy neutrinos ever observed. Further analysis and additional data revealed that these events formed the tail of a spectrum that is inconsistent with the background from neutrinos produced by cosmic ray interactions with the atmosphere. While the measured rates agree with theoretical predictions of an astrophysical neutrino flux, many questions remain. Where did they come from? Does the spectrum abruptly cut off just above a PeV, or is it steeply falling?  I will present the latest results from IceCube, and discuss future plans.
