Modeling individual nearby radio galaxies as ultra-high-energy cosmic-ray accelerators
Andressa Colaço, Gabriel Azeredo, Isadora Parillo +2
Nearby radio galaxies are among the most promising candidates for the acceleration of ultra-high-energy cosmic rays (UHECRs). In this work, we develop a physically motivated, sourc…
