Abstract
The IceCube Neutrino Telescope has observed a diffuse all-flavor astrophysical neutrino flux above $30\,\mathrm{TeV}$. The neutrino flux is currently compatible with an isotropic distribution; no astronomical counterparts have been identified yet. Here, we propose a binned forward-folding likelihood fit of the available neutrino data to search for integrated emission in the Galactic plane. We use two independent neutrino samples, one consisting of all-sky all-flavor events with deposited energies larger than $1\,\mathrm{TeV}$ whose interaction vertex is contained in the detector's fiducial volume, the other of up-going muon neutrinos; both samples are integrated over a time period of six years. By performing a joint analysis of through-going and starting events, degeneracies between Galactic and extra-galactic neutrinos can be resolved and uncertainties in the atmospheric neutrino fluxes are better controlled. We present preliminary sensitivities for different models of neutrino emission from the Galactic plane.
