The opacity could be alleviated if photons oscillated into hypothetical axion-like particles (ALPs) in ambient magnetic fields, leading to a $\\gamma$-ray excess especially at high optical depths that could be detected with imaging air Cherenkov telescopes (IACTs).\n  Here, we introduce a method to search for such a signal in $\\gamma$-ray data and to estimate sensitivities for future observations.
