Diffuse Neutrinos & Gamma Rays - Complementary Views on the High-Energy Universe, Markus Ackermann, DESY
Non-thermal processes in our cosmos have been studied for several decades through the observation of individual sources and diffuse emission in γ rays. However, the universe is transparent to γ rays only at MeV and GeV energies. Above 100 GeV, they are increasingly absorbed in interactions with the omnipresent radiation background from stars and the CMB. At TeV energies γ-ray observations are...
