Figure 2

Density plots of the solutions represented in Fig. 1, in particular: (a,b) correspond to a = 0.35, (c,d) correspond to a = 0.25, (e,f) correspond to a = 0.07, left column represents two-component model with cross-diffusion, right column the corresponding reconstructed three-component model with self-diffusion only. White corresponds to u = −0.3, black corresponds to u = 1.1. The insets in panels (e,f) (designated by solid blue lines) show selected fragments of the density plots magnified, to reveal the fine structure of group quasi-solitons (see also Apple QuickTime movies corresponding to these regimes in Supplementary information).
