[34.01] Searching for Astrophysical Neutrinos at the Energy Frontier

S. Barwick (University of California, Irvine)

The AMANDA-II high energy neutrino detector began operation at the South Pole in January, 2000 with the expectation of ushering in the era of multi-messenger astronomy. This telescope was originally conceived to detect neutrinos with energies of the order of 1-10 TeV, although it is capable of detecting neutrinos over a much broader range of energies. Recently, a new analysis technique has been developed to extend the sensitivity of the detector to neutrino energies beyond 104 TeV.

I will summarize the results of searches for diffuse and point sources of TeV-scale neutrinos from AMANDA, and then describe new and radically different detectors designed to measure diffuse sources of neutrinos with energies above 104 TeV. One such idea is called ANITA, a balloon-borne telescope that can view areas as large as 1 million square kilometers. If all goes as planned, ANITA will be the first detector capable of measuring the flux of neutrinos emitted by the interaction between high energy cosmic rays and cosmic microwave background photons, known as the GZK neutrinos.
