Nonthermal emission in the starburst galaxies M82&NGC253

Research output: Contribution to journalArticlepeer-review


Detection of high-energy γ-ray emission from the nearby starburst galaxies M82 and NGC253 establishes, for the first time, 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 γ-ray measurements in order to determine the particle spectral properties and energy densities in these galaxies.
