Multi-Messenger galactic supernova analyses — •David Kappesser and Lutz Köpke for the IceCube collaboration — Johannes Gutenberg-Universität Mainz

Supernovae in our galaxy are rare phenomena. It is therefore essential that a core collapse supernova can be investigated by as many experiments as possible. This includes neutrino detectors, gravitational wave interferometers as well as detectors that cover the electromagnetic spectrum. A collaboration between various experiments has been established in order to develop tools for a combined analysis of neutrino data that takes the strengths of individual detectors into account. As a first step, the combination of simulated IceCube and JUNO data has been studied and a combined analysis of LIGO and IceCube has been performed. Within the SNARE(SuperNova Advance Readiness Exercise) project, a core collapse simulation with hidden features will be prepared by theorists and subsequently be transformed into signals of various detectors. The goal of this exercise is the determination of the characteristics of the supernova signal with individual detectors and to use the prepared simulated data to set up a combined analysis framework and common analysis tools.
