[FIGURE 37] Simulations indicate that in a galaxy, dark matter should have a cuspy density distribution in which matter is heavily concentrated near the center. But observations indicate a cored profile—a smoother, less dense matter distribution in the central region. In both cases, the density peaks in the center as indicated by the figure, but the cuspy distribution peaks far more sharply.
This figure is practically meaningless. What is the sphere? What are the two lines? What is p?
A legend might help.
The cored vs. cuspy names don't help either, and the figure note changes some of the definition.
