Left panel: SFR-M_⋆ plane at z = 2.8 for the Gonzalez-Perez et al. (2014) model. The coloured contours show the number densities of quasars with luminosities in the Bj band >10^44.5 erg s^-1. The black contours show the number densities of the subset of bright quasars that have at least one companion galaxy with SFR> 100 M_⊙ yr^-1 at a physical distance <1 Mpc. The red contour shows the subset of bright quasars that have at least one companion galaxy with SFR> 100 M_⊙ yr^-1 at a physical distance <100 kpc. Solid and dashed contours, and the dashed black line same as in Fig. 3. The figure shows that the subset of bright quasars with nearby star-forming galaxies are typically on the main sequence of galaxies or below. Right panel: as in the left panel but for a variant of the Gonzalez-Perez14.GRP model.
