WIDG Seminar, Jorge Torres, Yale University, “Tuning into neutrinos on the radio with the Askaryan Radio Array”

Neutrino Astronomy allows us to observe the distant, high-energy universe. It was born when the IceCube experiment reported the first observation of neutrinos with energies in the PeV regime. Neutrinos with higher energies, called ultra-high energy (UHE) neutrinos, are predicted to exist, but they have not been observed yet due to their extremely low flux, requiring immense detection volume. An alternative to overcome this challenge is to use the radio-detection technique, which uses antennas to observe radio waves (Askaryan radiation) emitted when UHE neutrinos interact with a dense medium. The Askaryan Radio Array (ARA) experiment is a detector based in the South Pole that uses the radio-technique. In this talk, I will discuss the physics behind the radio detection of UHE neutrinos, the latest results from the ARA experiment, and current efforts toward direction reconstruction of neutrino events.
In-person attendance will be capped at 20 people on a first-come, first-served basis, according to the current Yale policies.
