Projected logarithmic density profile slope as a function of projected enclosed mass. For our most highly resolved simulation evolved in isolation (simulation Q from Table A.1), we show how the projected logarithmic density profile slope, γ_2D, and the projected enclose mass, M_<r2D, evolve with time. We display γ_2D and M_<r2D for several radii r_2D (see inset for legend). The larger circles mark the value at the beginning of the simulation, i.e. for an NFW profile. Moreover, the small white dots are placed equidistant in time, every 0.98 Gyr.
