Core radii r_c (left), core densities δ_c (middle), and core masses M_c (right) versus M₂₀₀ for halos in cosmological simulations of SIBEC-DM with R_c = 1 kpc, 3 kpc, and 10 kpc, using the Burkert profile. The upper plots show the scatter of halos at z = 0.5, with the fitted scaling Eqs. (44)–(46) shown in dashed lines, compared to the SPARC dataset (Li et al. 2020) and Milky Way dSphs (Salucci et al. 2012). The lower plots show the fitted median (solid) and the first and third quartiles (shaded) at several redshifts using Theil-Sen regression. The results from SPARC and the dSphs are also shown. In the scatter plot for r_c the core radii R_c are indicated in dotted colored lines.
