Abstract: Popular explanations of the anomalous transparency of the Universe for energetic gamma rays include conversion of photons into hypothetical axion-like particles (ALPs) and back in astrophysical magnetic fields. \J{This could either } happen in the gamma-ray source and in the Milky Way, or the photon-ALP oscillations could take place in the intergalactic magnetic fields all along the way between the source and the observer. Given recent astrophysical constraints on ALPs and on intergalactic magnetic fields, these two mechanisms imply very different ALP parameters: masses and couplings. Therefore, confirmation of the anomalies and identification of one of the scenarios would mean cornering of ALP parameters to a particular narrow region.
