This study investigates low luminosity Fanaroff-Riley Type 0 (FR0) radiogalaxies as a potentially significant source of ultra-high energy cosmic rays(UHECRs). Due to their much higher prevalence in the local universe compared tomore powerful radio galaxies (about five times more than FR-1s), FR0s mayprovide a substantial fraction of the total UHECR energy density. To determinethe nucleon composition and energy spectrum of UHECRs emitted by FR0 sources,simulation results from CRPropa3 are fit to Pierre Auger Observatory data. Theresulting emission spectral indices, rigidity cutoffs, and nucleon fractionsare compared to recent Auger results. The FR0 simulations include theapproximately isotropic distribution of FR0 galaxies and various intergalacticmagnetic field configurations (including random and structured fields) andpredict the fluxes of secondary photons and neutrinos produced during UHECRpropagation through cosmic photon backgrounds. This comprehensive simulationallows for investigating the properties of the FR0 sources using observationalmulti-messenger data.
