Density profiles of halos whose random particle velocities have been reduced by factors of 3 (dot‐dashed line), 10 (long‐dashed line), and 100 (dotted line) and increased by a factor of 3 (short‐dashed line), compared to the reference halo (solid line). Reducing random velocities means that the angular momentum of dark matter particles is reduced, which results in steeper central density slopes. The limiting slope ﹩\alpha =2﹩ is discussed in § 5.1, and the progressive shallowing of the slopes is discussed in § 5.3.
