Search for neutrino emission in the Galactic plane with IceCube using starting events — •Kai Krings for the IceCube collaboration — Technische Universität München, Physik-Department, James-Franck-Str. 1, D-85748 Garching

The IceCube Neutrino Telescope has observed a diffuse all-sky all-flavor astrophysical neutrino flux above 30 TeV; no sources have been identified yet. We want to challenge the question if the flux is partly of Galactic origin, by searching for neutrino emission in the Galactic plane. Complementary to the search with up-going muon neutrinos, which is constrained to the northern sky only, we use events from both hemispheres with energies above 1 TeV and interaction vertices inside the fiducial volume of the IceCube detector. Thus, the entire Galactic plane can be observed, including the Galactic Center. We present the sensitivity of a likelihood-based analysis to models that predict cosmic-ray induced neutrino emission in the Galactic plane, using seven years of data.
