They can be detected using a peculiar effect: axions can be converted to photons in a strong magnetic field. The ADMX experiment consists of a closed cavity with a resonator and a strong magnetic field. It systematically scans through the resonator frequencies, hoping to observe axion dark matter - to - photon conversions in its cavity.
Would that look to the sensors like a photon just appearing out of nowhere?
Yes, exactly, although I think to make a detection one would need more than one converted photon. You have a closed cavity, and suddenly there would be electromagnetic waves in it:
