Left: Redshift evolution of the galaxy stellar mass function, the data points correspond to the compilation used in Fontanot et al. (2009, see complete reference list for their Fig. 1). Right: Redshift evolution of the bolometric QSO/AGN-LF; the shaded regions show the expected space density from the empirical estimate of Shen et al. (2020). The black solid, black dashed, and red solid lines refer the GAEA model version presented in DL24 and run on the MS, MSII, and PMS simulations, respectively.
