Model predictions for the evolution of the M_BH − M_* relation. Left panel: comparison of the observed (orange dots) and predicted M_BH − M_* relation for galaxies in the redshift range 1.2 ≤ z ≤ 1.7. The color code corresponds to the logarithm of the fraction of galaxies with different M_BH in a given log M_* bin. The data are taken from Ding et al. (2020). The total predicted distribution of model galaxies in the M_BH − M_* plane is shown by the blue contours, and the red region corresponds to the subsample of model galaxies that satisfies the same selection criteria as the observations. Right panel: distribution of the residuals for the observations (orange histogram), the model galaxies (blue histogram), and the model galaxies resulting in simulations with the isotropic feedback model implemented in previous versions of our SAM (green histogram, taken from Ding et al. 2020). Model galaxies are selected so as to mimic the observational measurement errors and selection effects (see text).
