摘要	Very-high-energy (E > 100 GeV) gamma-ray observations offer the possibility of indirectly detecting the presence of axion-like particles (ALPs). This paper focuses on detecting photon-ALP oscillations in gamma-ray spectra from distant sources in astrophysical magnetic fields. Strong evidence indicates that 1) photon-ALP oscillations can effectively decrease photon absorption at energies of several tens of TeV-caused by the extragalactic background light-to a level able to better explain the observational data, and 2) the impact of magnetic-field models in photon-ALP beams crossing several magnetized media is significant. We revisit the expected signature for the photon-ALP oscillation effects on gamma-gamma absorption in the TeV spectra of Mrk 501. The result is that the photon-ALP beam propagation with mass m(a) similar to 10(-10) eV and two-photon coupling constant g(a gamma) similar to 0.417 x 10(-11) GeV-1 crossing reasonable magnetic field scenarios considered here can roughly reproduce the observed TeV gamma-ray spectra for Mrk 501.
