Description
The Payload for Ultrahigh Energy Observations (PUEO) is a long-duration balloon payload that flew for 23 days during the 25/26 austral summer in search for ultrahigh energy (UHE) neutrinos. Using a compact antenna distribution and a phased-array trigger, PUEO monitored the Antarctic ice for Askaryan emission produced by neutrinos interactions at energies > 1EeV and is designed to be the world’s most sensitive experiment in this regime. Additionally, PUEO is sensitive to radio emission from UHE cosmic ray and tau neutrino decay air showers, utilizing a Low Frequency instrument to extend PUEO’s sensitivity to these science channels. This poster will describe PUEO’s flight (including launch, operations, and termination), and present progress on the calibration and analysis of the collected data.
