    Active Galactic Nuclei (AGN)
    For ultra-high-energy cosmic rays (UHECRs)/), those exceeding $10^{18}$ eV, galactic sources are generally deemed insufficient due to confinement issues within the galactic magnetic field. Consequently, Active Galactic Nuclei (AGN)/), particularly those associated with powerful relativistic jets, are the favored candidates for UHECR/) generation. The conf…
