Resonant cavities enhance axion dark matter decay to two photons via the Purcell effect, offering a competitive search method implementable with pre-existing heterodyne detection schemes.
DALI has sensitivity to axion streams spanning two decades in mass that matches photon coupling strengths of representative axion models.
