Core formation. Upper panel: initial (dashed) and the final (solid) density profiles for the three halo models. Both NFW models clearly show that a core was developed at 20 (NFW1) and 10 (NFW2) kpc, respectively. Middle panel: initial circular velocity (dash-dotted line) and the initial 3D velocity dispersion (solid line with stars). Lowest panel: same kinematic profiles at the end of the simulation.
