Particle Astrophysics at the Highest Energies with the Greenland Neutrino Observatory (GNO)

Ultra-high energy neutrino astronomy sits at the boundary between particle physics and astrophysics.  Through neutrino astrophysics, we can probe the nature of the ultra-high energy universe in a unique way, and test our understanding of particle physics at energies much greater than those achievable at particle colliders. The best limit to date on the flux of ultra-high energy neutrinos comes from the ANITA experiment, a balloon-borne radio telescope designed to detect coherent radio Cherenkov emission from cosmogenic ultra-high energy neutrinos.  The future of ultra-high energy neutrino detection lies with ground-based radio arrays, which would represent an enormous leap in sensitivity.  I will discuss our plans for the Greenland Neutrino Observatory (GNO), a new radio detector at Summit Station in Greenland that will have the sensitivity to discover the highest energy neutrinos even in the most pessimistic of models and study the high energy cutoff of the astrophysical neutrino flux recently detected by IceCube.
