Experimental Constraints on the Axion Dark Matter Halo Density
arXiv:astro-ph/0104200 · doi:10.1086/341130
Abstract
Most of the mass of the Milky Way galaxy is contributed by its halo, presumably in the form of non-interacting cold dark matter. The axion is a compelling cold dark matter candidate. We report results from a search which probes the local galactic halo axion density using the Sikivie RF cavity technique. Candidates over the frequency range 550$$ $\le$ f $\le$$μ\le$$_{a}\leμ^3$ of mass density to the local dark matter halo over this mass range.
