Star-forming MS of galaxies in the DIANOGA PCs (orange) and in the cosmological box (green). Solid lines define the median SFRs of all star-forming galaxies within each stellar mass bin, while the shaded areas mark the 16th–84th percentile intervals. The star symbols represent proto-BCGs identified in the simulations, color coded according to the mass M_200c of the main progenitor halo of each PC. Black diamonds and green dots are data for the Spiderweb PC from Pannella et al. (in prep.) and from Pérez-Martínez et al. (2023), respectively. The blue line is the best fit for the observed field star-forming MS by Schreiber et al. (2015) at z = 2.2. The red bar shows the estimated SFRs for the Spiderweb galaxy from measurements by Seymour et al. (2012) and Drouart et al. (2014). Simulated SFRs are averaged over 200 Myr (see text).
