Searching for Axion Dark Matter using Radio Telescopes
  We investigate the use of next generation radio telescopes such as the Square
Kilometre Array (SKA) to detect axion two-photon coupling in the astrophysical
environment. The uncertainty surrounding astrophysical magnetic fields presents
new challenges, but with a frequency range corresponding to axions of mass
$1.7-57\mu$eV and a spectral profile with a number of distinguishing features,
SKA-mid offers a tantalising opportunity to constrain axion dark matter
properties. To determine the sensitivity of SKA-mid to an axion signal, we
consider observations of the Galactic centre and interstellar medium, and find
that this new telescope could allow us to probe axion couplings
$\gtrsim10^{-16}$GeV$^{-1}$.
