Pointing to a supernova with the DUNE experiment

When a core collapse supernova occurs, neutrinos are emitted with a high luminosity and they will arrive on Earth long before any electro-magnetic signal. A fast and precise detection of these neutrinos is highly desired to be able to reconstruct the burst direction to point optical detection systems there in a multi messenger approach. These neutrinos also provide a unique opportunity to derive new insights on astro and particle physics.

The Deep Underground Neutrino Experiment (DUNE) will be capable of such a detection due to its large active mass of up to 40 ktons of liquid argon. The experiment will be located underground below an overburden of about 1500 m. The time projection chambers (TPCs) possess an excellent 3D imaging capability facilitating the directional reconstruction of the neutrino-induced tracks.

In my talk, I will present the pointing resolution achievable with the current analysis framework based on the detection of electron neutrino scattering on electrons. Moreover, I will point out a way to transfer the existing pipeline to a fast online pointing analysis, which is required for the multi messenger approach.
