Abstract

Cold dark matter in the Milky Way halo may have structure defined by flows with low velocity dispersion. The Axion Dark Matter eXperiment high resolution channel is especially sensitive to axions in such low velocity dispersion flows. Results from a combined power spectra analysis of the high resolution channel axion search are presented along with a discussion of the assumptions underlying such an analysis. We exclude Kim-Shifman-Vainshtein-Zakharov axion dark matter densities of ρ 0.2GeV/cm3 and Dine-Fischler-Srednicki-Zhitnitskii densities of ρ 1.4GeV/cm3 over a mass range of m _a=3.3μeV to 3.69μeV for models having velocity dispersions of Δβ3×10 ^-6.
