DM profiles and inner slope of the sample. Left-hand panel: DM profiles for the galaxies containing the most massive (H0, solid lines) and least massive (H11, dotted lines) SMBHs. The configuration without an AGN is shown in green, and the AGN run in blue. The grey area shows radii below the simulations’ physical softening length. Right-hand panel: Ratio between the mean DM density profile in the inner region of each galaxy (within the softening length and 1 kpc) in the AGN vs non-AGN configuration, plotted against the z = 0 SMBH mass.
