Does anyone know where I can find either a printed version or, better, a downloadable dump of data giving me the density profile of the Milky Way? I'm looking to put together a quick-and-dirty simulation of the Milky Way and the bulge data is very important for looking at the velocity profiles.

  • $\begingroup$ Googling "Phil Plait" and "Emily Lakdawalla" may get you going. They both have great astronomy blogs. $\endgroup$ – Carl Witthoft Sep 30 '14 at 11:42
  • $\begingroup$ So is it the density profile you need, or would a description of the potential suffice? $\endgroup$ – Rob Jeffries Sep 30 '14 at 19:09
  • $\begingroup$ I'm looking for either a chart (or formula) which describes the way the density of matter (stars, ISM) changes as a function of the distance from the galactic center. I'm not sure to what 'potential' you are referring. $\endgroup$ – Quarkly Oct 1 '14 at 15:28
  • $\begingroup$ @DRAirey1 The gravitational potential (including dark matter). You mention stars and ISM, but these contribute the minority of the density of the Milky Way. What are you trying to simulate? $\endgroup$ – Rob Jeffries Oct 1 '14 at 18:31
