N2 - The energy density of cosmic ray protons in star forming galaxies can be estimated from π0-decay γ-ray emission, synchrotron radio emission, and supernova rates. To galaxies for which these methods can be applied, the three methods yield consistent energy densities ranging from Up ∼ 0.1 - 1 eV cm-3 to Up ∼ 102 - 103 eV cm-3 in galaxies with low to high star-formation rates, respectively.
