Disk-galaxy density distribution from orbital speeds using Newton's law, version 1.1
Kenneth F. Nicholson
Abstract
Given the dimensions(including thickness) of an axisymmetric galaxy, Newton's law is used in integral form to find the density distributions required to match a wide range of orbital speed profiles. Newton's law is not modified and no dark-matter halos are required. The speed distributions can have extreme shapes if they are reasonably smooth. Several examples are given.
