The formation of disc galaxies is generally believed to involve the dissipative collapse of primordial gas clouds, moving in the potentials of dark, self-gravitating massive halos. Until now, most theories have considered only spherically symmetric collapse, with the luminous disc being formed out of a plane of cold gas which is in centrifugal equilibrium. However, it is unlikely that the halo potential will in fact be spherical.
