Description

Dark matter direct (and indirect) detection experiments usually can only deter-
mine a specific combination of a power of the coupling and the dark matter density. This is also true for axion haloscopes which are sensitive to the product g^2ρ, the combination of axion-photon coupling squared and the dark matter density. We show, that in the lucky case when we intersect with a so-called minicluster of a suitable size, we can utilize the spectral information available in haloscopes to determine the gravitational potential of the mini-cluster. We can the use this to separately measure coupling and density of the mini-cluster.
