Dark matter halos 465(a)(b)
Figure 15.19. (a) Density profiles of halo A simulated with different mass and force
resolutions. The profiles are plotted down to the formal force resolution of each simulation.
(b) The profiles plotted down tofour formal resolutions. It is clear that for vastly
different mass (from 2000 to 120 000 particles in the halo) and force (from 3. 66 h−^1 kpc to
0. 23 h−^1 kpc) resolutions, convergence is reached at these scales.
