Title: Vortices in Light Dark Matter

Abstract: In a galactic halo like the Milky Way, a bosonic dark matter particle lighter than about 1 eV has a de Broglie wavelength larger than the average inter-particle separation so the dark matter is well described by a set of classical waves. The interference of these waves inside a halo inevitably leads to vortices, locations where chance destructive interference takes the density to zero. I will discuss the properties of these vortices along with possible observational signatures.
