<i>γ</i>-ray/infrared luminosity correlation of star-forming galaxies
Context. Near a dozen star-forming galaxies have been detected in gamma-rays by the Fermi observatory in the last decade. A remarkable property of this sample is the quasi-linear relation between the gamma-ray luminosity and the star formation rate, obtained assuming that the latter is well traced by the infra-red luminosity …
