The behaviour of low mass scalar fields around black holes is of great interest in the context of dark matter models consisting of a massive scalar field (such as the axion) and the new era of gravitational wave astronomy. I will discuss three related projects concerning the accretion of minimally coupled low mass scalar fields around black holes: the growth of accretion driven scalar hair around Kerr black holes (, the quasi-normal modes of growing hairy Schwarzschild black holes (, and our preliminary work on the accretion of scalar fields around black hole binaries. Throughout I will describe the prospects for detectable gravitational wave signals, and the methods we used to explore the dynamics of these systems.
