摘要：
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 approximation, we perform a GPU-accelerated interferometric reconstruction of the event vertex. We also demonstrate how use of both direct and reflected/refracted radio signals can allow reconstruction of the distance to the interaction vertex, an important step towards neutrino energy reconstruction.
