135 h: 16:00 An Indirect Search for Axion Dark Matter
Sam Witte In this talk I will discuss the possibility of detecting the decay of axion (and axion-like) dark matter to two photons. I will show that on astrophysical scales the axion to two-photon decay process dominates over the more conventionally considered process of non-resonant axion-photon conversion. Furthermore, I will demonstrate that the decay process can be significantly enhanced when in the presence of large radio backgrounds. Astrophysical signatures and sensitivities for near future experiments will also be presented.
