摘要: We show that cold dark matter axions thermalize and form a Bose-Einstein condensate (BEC). obtain the axion state in homogeneous isotropic universe, derive equations governing small perturbations. Because they BEC, differ from ordinary nonlinear regime of structure formation upon entering horizon. Axion BEC provides mechanism for production net overall rotation halos, alignment cosmic microwave anisotropy multipoles.
