Correlation of AGN and host galaxy properties. The top panel presents the L_bol as a function of SFR. Different symbols and colours correspond to different redshift intervals, as shown in the legend. The solid line indicates the local M_BH − M_* relation that would be expected from exactly simultaneous evolution of the SMBH and the host galaxy. AGN that lie above this line live in galaxies in which SMBH growth is dominant. AGN that lie below the line are systems in which galaxy growth dominates. The bottom panel shows the distribution of AGN (red circles) and SF (blue circles) dominant systems in the M_BH − M_* space. The dashed lines are the same as those used in Fig. 4.
