Scientific paper

A previous model of dynamic gravitational interaction (Ghosh, 1984) is used to explain the distribution of matter in rotating spiral galaxies that produces the observed flat rotation curves. In the present work, spiral galaxies are assumed to be axisymmetric thin disks truncated at a suitable radius within which most of the galactic matter is contained. It is found that the velocity-dependent inertial inductions arising from the proposed model can act as a servomechanism which is capable of providing the necessary matter distribution.
