Description
Detection of high-energy gamma-ray emission from starburst galaxies (such as nearby M82 and NGC 253, and faraway Arp 220) has established a direct link between leptonic and hadronic processes in an extragalactic non-AGN environment. We review the most relevant aspects of these processes,and contrast theoretical predictions with available radio and gamma-ray measurements, in order to determine the particles' spectral properties and energy densities in these galaxies.
