Correlation between bolometric luminosity and outflow mass-loss rate in IllustrisTNG simulations. Red square symbols represent galaxies where the AGN has ≥20% contribution to L_bol, while blue symbols are all other galaxies. The median mass-loss rate in bins of L_bol is shown by the black symbols. The main correlation, log(Ṁ_outf) = 0.54 log(L_bol) − 4.13, is shown by the red line.
