Effects of galaxy formation on dark matter haloes

We have studied six galaxy-sized haloes of the Aquarius Project, finding, in agreement with previous results, that baryon condensation leads to an increase of the dark matter concentration. We find that in all cases the velocity dispersion increases monotonically with radius. The shape and concentra...
