Dark Matter Scaling Relations

arXiv:astro-ph/0004397 · doi:10.1086/312747

Abstract

We establish the presence of a dark matter core radius, for the first time in a very large number of spiral galaxies of all luminosities. Contrary to common opinion we find that the sizes of these cores and the " DM core problem" are bigger for more massive spirals. As a result the Burkert profile provides an excellent mass model for dark halos around disk galaxies. Moreover, we find that the spiral dark matter core densities and core radii lie in the same scaling relation of dwarf galaxies with core radii upto ten times more smaller.
