Predicted relations between M_BH and the stellar and DM properties of the host galaxies. The M_BH − M* relation (panel A), the M_BH − M_h relation (panel B), the f_* − M_BH relation (panel C), and the f_* − M_h relation (panel D) are compared with the data from Marasco et al. (2021; orange points). In panel A we also report data from Sahu et al. (2019a,b; black dots). The gray contours show the predictions of our model in the absence of AGN feedback. In all panels and for each abscissa value, the color code corresponds to the logarithm of the fraction of galaxies with different values of the quantities in the y-axis.
