Exploring the Ultra-High Energy Universe
Using Radio Detection Techniques

Abstract: Ultra-high energy neutrino astronomy is a rapidly emerging field at the crossroads of 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 recent results in the field, including the most recent neutrino search analysis and the surprising detection of radio synchrotron emission from UHE cosmic rays with ANITA. I will also discuss plans for the upcoming third flight of ANITA and ideas and plans for future ground-based radio arrays.
