Abstract
Gravitational N-body experiments can be used to simulate the stability of model galaxies, the evolution of disk-shaped galaxies, and spiral structure. However, they usually suffer from overheating (i.e., large velocity dispersions of the interacting stars), and non-flat rotational curves. For the N-body simulations to agree with observation of actual normal galaxies, it is necessary to assume the presence of a large spherical slowly rotating subsystem (a halo) with the bulk of the galactic mass. An Alfvén model based on the interaction of two galactic-sized plasma filaments (or equivalently, two inviscid fluid vortices) may explain interesting features of galactic morphology including double radio lobes and the presence of extragalactic jets from classic double radio sources.
