Event Reconstruction for the Cascade Real-Time Alert Stream in IceCube — •Mirco Hünnefeld and Jan Soedingrekso for the IceCube collaboration — TU Dortmund, Germany

IceCube is a neutrino detector located at the geographic South Pole, instrumenting a cubic kilometer of glacial ice. A major goal of IceCube is the detection of astrophysical neutrino sources. Therefore, a real-time alert system was implemented to enable multi-messenger astronomy. Events that pass certain selection criteria are reconstructed in real-time on-site at the South Pole. If these events meet the requirements, they are sent out as alerts to telescopes around the world, enabling follow-up observations. Precise and fast reconstruction methods are necessary to abide the harsh resource constraints given on-site. The inclusion of cascade-like events harbors further challenges due to their inherently difficult angular reconstruction. In this talk, a deep learning-based reconstruction method is presented, which enables the accurate and fast reconstruction of cascade-like events and thus the implementation of a cascade alert stream.
