Abstract
A hot spot was found in the analysis of 7.5 years of data in the high-energy starting event sample of IceCube below the Galactic plane. We studied the cosmic rays density arround nearby, young supernova remnants assuming anisotropic diffusion. We then computed neutrino and gamma ray fluxes, combining cosmic rays densities with the distribution of matter in the nearby interstellar medium from a recent dust map survey. Cosmic rays from the cygnus loop produce a hot spot in neutrino close to the IceCube hotspot and with an intensity corresponding to two neutrino events.
