Stellar mass density as a function of cosmic time (redshift is given in the top label). Black and red points correspond to the full and quiescent populations, respectively. The circles correspond to our new results using UltraVISTA. Solid and open red circles correspond to the two-colour and sSFR selected quiescent galaxies, respectively. The green shaded area corresponds to the cosmic SFR compiled by Behroozi et al. (2013) and integrated over cosmic time as described in Sect. 6.1. The dashed line corresponds to the best fit over the mass density data.
