We introduce a new macroscopic model to simulate in-ice radar detection of high-energy particle cascades. Ultra-high-energy cosmic events can reach the polar ice as a cosmic-ray extensive air shower or as a single neutrino. In both cases, the interaction with the ice media produces a high-energy particle cascade, which leaves a short-lived plasma trail composed of ionized ice electrons. Unlike...
The Askaryan Radio Array (ARA) is an in-ice radio detector at the South Pole that targets radio emission from neutrino-induced particle cascades. Designed to detect neutrinos above 10 PeV, ARA has been taking data for over ten years and includes five independent stations. The newest ARA station is equipped with a phased array trigger, which lowers the trigger threshold compared to previous ARA...
We present an end-to-end reconstruction of the neutrino energy, direction and flavor from shallow in-ice radio detector data using deep neural networks (DNNs). For the first time, we were able to determine the neutrino direction with a few degrees resolution also for the complicated event class of electron neutrino charged-current interactions where the shower development is impacted by the...
The detection of high-energy neutrinos in the EeV range requires new detection techniques to cope with the small expected flux. The radio detection method, utilizing Askaryan emission, can be used to detect these neutrinos in polar ice. The propagation of the radio pulses has to be modeled carefully to reconstruct the energy, direction, and flavor of the neutrino from the detected radio...
