Description
It was found recently that dark matter axions thermalize and form
a Bose-Einstein condensate (BEC). This provides an opportunity to
distinguish axions from other forms of dark matter on observational
grounds. I'll show that if the dark matter is axions, tidal torque
theory predicts a specific structure for the phase space distribution
of the halos of isolated disk galaxies, such as the Milky Way. This
phase space structure is precisely that of the caustic ring model,
for which observational support has been found earlier. The other
dark matter candidates predict a different phase space structure
for galactic halos. These findings imply that the dark matter
is axions.
