Distribution of AGN in the sṀ/sSFR–M_BH/M_* space. In the top panel, different colours and symbols correspond to a different redshift bin, as shown in the legend. The bottom panel presents the distribution of SF (blue circles) and AGN (red circles) in the sṀ/sSFR–M_BH/M_* space. Sources marked with a square are classified as galaxies with overweight SMBHs, while those marked with a triangle are classified as galaxies with underweight SMBHs. The classification is based on the location of the AGN in the M_BH − M_* plane relative to the line that describes the best fit on our M_BH − M_* measurements (see text and Fig. 4 for more details).
