The IceCube Neutrino Observatory is a kilometer-scale neutrino telescope located at the South Pole underneath the Antarctic ice. In the last years IceCube has provided evidence of a diffuse flux component of high-energy astrophysical neutrinos at the level of 10-8 GeV cm-2 s-1 sr-1 per flavor. The origin of these neutrinos remains, however, unknown. Ongoing analyses are trying to solve this...
38. Gamma-ray, Cosmic-ray, and Neutrino Connections from the Acceleration of Cosmic Rays at SNR Shocks in the Milky Way and other Star-Forming Galaxies
Charles Dermer (Naval Research Laboratory)
Results relevant to the question of Galactic cosmic-ray origin are presented. These include updates on hadronic strong-interaction cross sections for the production of secondary gamma rays, leptons and neutrinos, and the use of these cross sections to reveal cosmic-ray interactions and the cosmic-ray spectra in analyses of Fermi-LAT data on supernova remnants and the diffuse Galactic gamma-ray...

Eta Carinae is the colliding wind binary with the largest mass loss rate in our Galaxy and the only one in which hard X-ray and gamma-ray emission has been detected. Eta Carinae is therefore a primary candidate to search for particle acceleration. We present preliminary gamma-ray data covering two periastron passages. The source variability can be compared with the results of hydrodynamic...
39. On the possible correlation of Galactic very-high energy source locations and enhancements of the surface density in the Galactic plane
Dr. Giovanna Pedaletti (DESY Zeuthen)
The association of very-high energy sources with regions of the sky rich in dust and gas has been noticed in the study of individual very-high energy (VHE; E > 100 GeV) sources. However, the statistical significance of this correlation for the whole population of TeV detections has not been assessed yet. To trace the material content, we make use of the recently released all-sky maps of...
