NPA Seminar, Steven Prohira, Ohio State University, "Toward Detection of UHE Neutrinos with the Radar Echo Telescope"
Detection of ultra-high-energy (UHE) neutrinos is the key to understanding the most energetic processes in the universe, namely, the sources of UHE cosmic rays which have been detected at earth with energies exceeding 1 Joule per nucleon. As UHE cosmic messengers, neutrinos are unparalleled for their ability to travel from source to Earth. Unfortunately, however, they are very difficult to detect, owing to their low flux and small interaction cross section.
