It has been found that there is a quasi-linear scaling relationship between the gamma-ray luminosity in GeV energies and the total infrared luminosity of star-forming galaxies, i.e., with 1. However, the origin of this linear slope is not well understood. Although extreme starburst galaxies can be r...
