Estimates of the Enclosed Mass and Its Distribution for Several Spiral Galaxies

Authors: Geoffrey M. Williams

Recently, high quality rotation curves for several spiral galaxies have become available from THINGS: The HI Nearby Galaxy Survey (Reference 1). This paper analyzes 15 of those galaxy rotation curves using the Newtonian Disk Model (Reference 2). The Model assumes that virtually all the mass of stars, gas, dust and dark-matter is contained as a “flattened” mass within the galactic disk, which extends out to the edge of the observable rotation. Estimates of the enclosed mass and its radial distribution are provided.
