Abstract: To date, most direct detection searches for axion dark matter, such as those by the Axion Dark Matter Experiment (ADMX) microwave cavity search, have assumed a signal shape based on an isothermal spherical model of the Milky Way halo. Such a model is not capable of capturing contributions from realistic infall, nor from a baryonic disk. Modern N-Body simulations of structure formation can produce realistic Milky Way-like halos which include the influences of baryons, infall, and environmental influences. An analysis of the Romulus25 N-Body simulation shows that the axion signals from MW-like halos are narrower than the SHM by nearly a factor of two, which has important implications for cavity searches. An improved signal shape and an account of the relevant halo dynamics are also given. This proceedings largely follows the recent publication by Lentz et al. [14] (L2017).
