Probing the angular and polarization reconstruction of the ARIANNA detector at the South Pole

Understand

The sources of ultra-high energy (UHE) cosmic rays, which can have energies up to 10^20 eV, remain a mystery.

• UHE neutrinos may provide important clues to understanding the nature of cosmic-ray sources.
• ARIANNA aims to detect UHE neutrinos via radio (Askaryan) emission from particle showers when a neutrino interacts with ice, which is an efficient method for neutrinos with energies between 10^16 eV and 10^20 eV.
• The ARIANNA radio detectors are located in Antarctic ice just beneath the surface.
