“Strong” version of the old core-cusp problem. Correlation between the averaged DM density within 2 kpc and the baryon-induced velocity at 2 kpc, V_b(2 kpc) (left panel: MLconst; right panel: L18a). The red-dotted curve is the correlation induced by the RAR in Eq. (7). This plot is closely related to the colour gradient visible in Fig. 5, as the average DM density within 2 kpc simply reads as , where R = 2 kpc.
