Equilibrium disk-bulge-halo models for the Milky way and Andromeda galaxies.

WIDROW L.M. and DUBINSKI J.

Abstract (from CDS):

We describe a new set of self-consistent, equilibrium disk galaxy models that incorporate an exponential disk, a Hernquist model bulge, an NFW halo, and a central supermassive black hole. The models are derived from explicit distribution functions for each component, and the large number of parameters permit detailed modeling of actual galaxies. We present techniques that use structural and kinematic data such as radial surface brightness profiles, rotation curves, and bulge velocity dispersion profiles to find the best-fit models for the Milky Way and M31. Through N-body realizations of these models we explore their stability against the formation of bars. The models permit the study of a wide range of dynamical phenomenon with a high degree of realism.
