A dark matter candidate lighter than about 30 eV exhibits wave behavior in a typical galactic environment.
Examples include the QCD axion as well as other axion-like-particles. We review the particle physics motivations, and discuss experimental and observational implications of the wave dynamics, including interference substructures, vortices, soliton condensation and black hole hair.
