Comparison between the local dimension, D, and the density, log(Σ), in the model considering all stars. Columns show the times 5, 6.5, 8.5, and 13 Gyr from left to right. Top: surface density map. Middle: local dimension map. Bottom: same as the top row but with contours at D = 1.9 (dashed) and D = 2 (solid) overplotted. The circles outlined with white dots show radii of 4 and 8 kpc, which are the limits used in most of our analysis. The rotation is anti-clockwise.
