WebWe discuss two kinds of signatures: (i) a peculiar spectral depletion due to gamma rays being converted into ALPs in the magnetic fields of efficient astrophysical accelerators according to the “Hillas criterion”, such as jets of active galactic nuclei or hot spots of radio galaxies; (ii) an appearance of otherwise invisible sources in the GeV or … Web3.1 The Hillas Criterion Magnetic ﬁelds play a key role in the existence of cosmic rays (CRs). The strength of the magnetic ﬁeld affects not only the acceleration process, but also imposes a limit on the highest energies that particles can obtain in a deﬁned region.
