Top panel: stellar mass as a function of redshift. The grey circles are the individual host galaxies of the BAT6 sample; the orange circles represent the median stellar mass at each redshift bin for hosts above the COSMOS2015UD mass completeness. The blue squares represent the median of the SFR-weighted stellar mass distribution of the COSMOS2015UD sample at each redshift bin. The blue line is the mass completeness of the COSMOS2015UD sample. Bottom panel: residuals of the difference between the blue and orange points. The errors are computed using Monte Carlo propagation and bootstrapping.
