Abstract: Astrophysical sources of energetic gamma rays provide the right conditionsfor maximal mixing between pseudoscalar axion-like particles and photons iftheir coupling is as strong as suggested by the PVLAS claim. This isindependent of whether or not the axion interaction is standard at all energiesor becomes supressed in the extreme conditions of the stellar interior. Theflux of such particles through the Earth could be observed using a metre long,Tesla strength superconducting solenoid thus testing the axion interpretationof the PVLAS anomaly. The rate of events in CAST caused by axions from the Crabpulsar is also estimated for the PVLAS-favoured parameters.
