Studying neutrino emission from the galactic plane with PLEnuM — •Anke Mosbrugger, Lisa Schumacher, and Christian Haack — Erlangen Centre for Astroparticle Physics (ECAP), Friedrich-Alexander-Universität Erlangen-Nürnberg

Diffuse neutrino emission from the galactic plane has long been expected given the observed gamma ray flux. One of the recent successes of the IceCube Neutrino Observatory was the observation of high-energy neutrinos from the galactic plane. This observation will give us further insight into cosmic ray propagation and galactic sources. However, due to its location at the geographic South Pole, IceCube's effective area in the direction of the galactic center region is limited. This limitation can be overcome by combining data from multiple neutrino telescopes with different fields of view, thereby increasing the analysis sensitivity. This concept is implemented in the Planetary Neutrino Monitoring System (PLEnuM). The PLEnuM software uses parametrized instrument response functions to facilitate the combination of datasets from multiple detectors. In this talk I will present the implementation of a galactic plane analysis in PLEnuM and show first results from the application of this method to public IceCube data. This work will enable projections and combined analyses for existing and future experiments such as IceCube-Gen2, KM3NeT, and P-ONE.
