sSFR as a function of galaxy stellar mass at different redshifts (as indicated in the panel) in NEWHORIZON with solid lines. The error bars stand for the error around the mean. The symbols correspond to the best fit from Behroozi et al. (2013) from their collection of observational data; their uncertainty is shown in dashed lines. The simulated sSFR show very little evolution with stellar mass at the two highest redshifts, while there is a significant quenching at the lowest redshifts for stellar masses above M_s > 10¹⁰ M_⊙. Simulated sSFR show a fair level of agreement with the observations.
