In the last decade, high-sensitivity radio and optical surveys have unveiled a new class of radio galaxies, called the Fanaroff-Riley type 0 (FR0). Due to their abundance in the local universe, this source class is of particular interest in the context of multi-messenger analyses as a possible neutrino emitter. The properties of FR0s at γ-ray energies are still largely unexplored due to the lack of observational data. However, observations have been made for the galaxies LEDA 55267, LEDA 57137, and LEDA 58287.
The multi-wavelength emission of these galaxies was modeled to determine the physical conditions under which the observed radiation is generated. The synchrotron, synchrotron self-Compton and the external Compton processes were considered. As a first result, we find that all the sources are consistent with being powered by the synchrotron self-Compton mechanism.
