Abstract
The Axion Dark Matter eXperiment is sensitive to narrow axion flows, given axions comprise a fraction of the dark matter with a non-negligible local density. Detecting these low-velocity dispersion flows requires a high spectral resolution and careful attention to the expected signal modulation due to Earth’s motion. We report an exclusion on the local axion dark matter density in narrow flows of ρa ≳ 0.03 GeV=cm3 and ρa ≳ 0.004 GeV=cm3 for Dine-Fischler-Srednicki-Zhitnitski and Kim-Shifman-Vainshtein-Zakharov axion-photon couplings, respectively, over the mass range 3.3 − 4.2 μeV. Measurements were made at selected resolving powers to allow for a range of possible velocity dispersions.
