Description

Neutrinos are the ideal messenger for high-energy astrophysics. Weakly interacting and uncharged, they propagate undeterred and unabsorbed through the universe. Through recent breakthrough discoveries of neutrinos with energies up to 220 PeV, we are starting to see hints of energetic neutrino sources for the first time. At the highest energies (>100 PeV), we can probe the most energetic sources of both neutrinos and cosmic rays, but current neutrino experiments become too small to observe a sizable flux. Radio experiments can achieve the large exposures necessary by taking advantage of the coherent broadband radio emission resulting from ultrahigh-energy (E>100 PeV) neutrino interactions as well as the large volumes visible from high elevations. In this talk, I will discuss the recent flight of the high-altitude balloon experiment PUEO in Antarctica.
