Specific black hole accretion rate (left panel) and sSFR (right panel) as a function of redshift for star-forming (SF, in green), quiescent (Q, in red), and starburst (SB, in purple) galaxies. The data points are placed at the median redshift of each mass bin and are coded in shape and color according to their median mass and type. Error bars represent the 90% confidence interval associated with each measure. We show an upper limit (the 95th percentile) for the data points whose sBHAR/sSFR 5th percentile is compatible with zero and for starburst galaxies at high redshift and low mass, where our sample is incomplete. The dot-dashed line is the best fit of the data to the curve sBHAR(sSFR) = δ (1 + z)^γ and is color-coded according to the galaxy type and mass bin.
