Hunting EeV Neutrinos with RNO-G and PUEO
Date: Thursday, February 9th
Time: 2:30 pm - 3:30 pm
Place: Chamberlin 4274
Speaker: Cosmin Deaconu, University of Chicago
Abstract: The Radio Neutrino Observatory - Greenland (RNO-G) and the Payload for Ultrahigh Energy Observations (PUEO) are two experiments under construction seeking to detect for the first time the elusive ultrahigh-energy (>~ 100 PeV) neutrinos. Such neutrinos are expected to be produced from interactions of cosmic rays with photons and potentially in astrophysical sources, but detection is challenging due to the low flux. Both experiments operate by attempting to detect the impulsive Askaryan radio emission produced in showers induced by energetic neutrinos interacting in glacial ice. PUEO is a long-duration balloon payload, expected to fly over Antarctica in 2024, while RNO-G uses embedded antennas in Greenland and started deployment in 2021. In this talk, I will discuss the science goals, design considerations and implementation progress of both experiments.
