Abstract

This thesis is a body of work that investigates the prospect of detecting an axion dark matter signature using radio telescopes. I present the key considerations for an astronomical search together with model flux and spectral profiles for a range of astrophysical sources. I focus on non-resonant conversion and explore the differences between the laboratory and sky based searches. I set out an equation for the photon production rate and examine the impact of the local environment. In so doing, I present results for the Milky Way, Galactic centre, Andromeda, Coma cluster and nearby pulsars using published axion models.
