On the origins of galaxies, galactic angular momenta, and galactic magnetic fields.
Abstract
It is shown that if one assumes the existence of a disordered cosmic magnetic field at recombination, then, provided the field varies on a comoving scale corresponding to a typical galactic mass, one can account for the existence of galaxies, galactic angular momenta, and galactic magnetic fields. The theory predicts the existence of a present-day intergalactic magnetic field of no more than about 1 billionth of a gauss varying on a characteristic length scale of the order of 1 Mpc.
