An analytical model for spherical galaxies and bulges

Abstract

A potential-density pair which closely approximates the de Vaucouleurs R^1/4^ law for elliptical galaxies is presented. It is shown that the intrinsic properties and projected distributions of this model can be evaluated analytically. In particular, the distribution function, density of states, and projected surface brightness and velocity dispersion are expressible in terms of elementary functions.
