Path followed by typical AGN hosts in the SSFR − M_∗ plane. The left panel refers to the IT scenario, the right panels to the DI mode. The main sequence computed from the model is represented by the black line (computed in the redshift range 0.5 <z< 0.8), while the blue and the red dotted lines mark the separation between the main sequence and the starburst/passive region. The position of AGN hosts is represented by a circle; if the circle is black, no AGN activity is present in the host, or AGN luminosity is below the threshold (L_X> 10⁴² erg s^-1). AGN activity above the threshold is represented by a coloured circle (the colour code is shown above each plot, and the AGN luminosity refers to X-ray luminosity in the 2−10 keV band). We also show the corresponding redshift near some circles; the hosts have been selected at redshift z = 0.5. At z = 0.5, AGN are characterized by luminosities Log L_X = 44.9 (left panel), LogL_X = 44.6 (right path, right panel) and Log L_X = 43.3 (left path, right panel).
