Neutrino Vertex Reconstruction in South Pole Ice

Neutrino Vertex Reconstruction in South Pole Ice

Reconstruction of potential ultra-high-energy (UHE) neutrino events at the Askaryan Radio Array (ARA) is complicated by the variable index of refraction of South Pole ice, leading to curved radio signal paths from the interaction vertex. Using a spline table framework for fast raytracing approximati...
