A model-independent measurement of the Galactic neutrino flux with IceCube — •Mirco Hünnefeld¹ and Ludwig Neste² for the IceCube collaboration — ¹TU Dortmund University, AG Rhode, Dortmund, Germany — ²Oskar Klein Centre, Stockholm University, Stockholm, Sweden

The IceCube Neutrino Observatory recently published results on the observation of high-energy neutrinos from the Galactic Plane. These neutrinos can be produced when cosmic rays interact at their acceleration sites and during their propagation through the interstellar medium. The observed neutrino signal appears consistent with diffuse emission from the Galactic Plane, potentially in combination with emission by a population of unresolved sources. Additional follow-up studies are required to further investigate the production mechanisms of the Galactic neutrino flux and to adequately correlate this observation with measurements by gamma-ray experiments. In this contribution, the development of such a follow-up analysis with IceCube is presented. The goal of the analysis is to provide a spatially-resolved, model-independent measurement of the Galactic neutrino flux.
