GeV Gamma-Ray Emission from Normal and Starburst Galaxies

Résumé

With the launch of the Fermi satellite and the advent of modern air-Cherenkov telescopes such as H.E.S.S. and VERITAS, star-forming galaxies have become a new class of gamma-ray sources that extend the study of cosmic-ray physics from the Milky Way to external galaxies. So far, 8 star-forming galaxies have been observed at GeV energies (SMC, LMC, Milky Way, M 31, M 82, NGC 253, NGC 1068, and NGC 4945) while 2 have been seen at TeV energies (M 82, NGC 253). In this paper, I review the observational status of the GeV observation of these galaxies, and I summarize the conclusions that have been drawn from these observations on cosmic-ray physics in normal and starburst galaxies.
