Primeval Turbulence?

Some difficulties with the Primeval Turbulence picture for galaxy formation are considered. It is shown that the evolution of the matter turbulence one decoupled from the radiation depends very much on the assumed turbulence velocity. If the velocity is small the turbulence simply adds to the amplitude of the growing density perturbation mode, an effect almost indistinguishable from the equally ad hoc assumption of a somewhat larger initial density perturbation. If the turbulence velocity field were made large enough to provide the angular velocity of the Galaxy, or the nominal peculiar velocities of galaxies, the galaxies would have formed sooner than one would otherwise have speculated.Research supported in part by the National Science Foundation.
