Star-forming main sequence, in terms of SFR (left panel) and sSFR (right panel), of the MQN01 galaxies clustered around the QSO (black stars), compared to the control-field sample (orange diamonds). The data are compared to the main sequence at z ≈ 3.25 derived from Speagle et al. (2014) (blue), Popesso et al. (2023) (green) and Koprowski et al. (2024) (purple). The X-Ray detected AGN are marked by yellow squares. The histograms on the top and right panels show the distribution of the SFR or sSFR and galaxies’ stellar mass, respectively, of the MQN01 galaxies (black) and of the control-field sample, together with their median values on top.
