      abstract     = {Cold dark matter axions thermalize through gravitational
                      self-interactions and form a Bose-Einstein condensate when
                      the photon temperature reaches approximately 500 eV. Axion
                      Bose-Einstein condensation provides an opportunity to
                      distinguish axions from the other dark matter candidates on
                      the basis of observation. The rethermalization of axions
                      that are about to fall in a galactic potential well causes
                      them to acquire net overall rotation, whereas ordinary cold
                      dark matter falls in with an irrotational velocity field.
                      The inner caustics of galactic halos are different in the
                      two cases.},
