Search for neutrino emission from the Galactic plane with IceCube using starting events — •Kai Krings for the IceCube collaboration — TU München, Physik-Department, Excellence Cluster Universe, Boltzmannstr. 2, 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, searching for an integrated neutrino signal along 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 starting inside 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 generic Galactic plane models, using two years of starting event data.
