Top panels: cumulative stellar mass distribution for the hosts of the BAT6 sample (orange) and the star-forming galaxies from the COSMOS2015 Ultra Deep catalogue (blue, left panel) and MOSDEF (blue, right panel) at 1 < z < 2. The COSMOS2015 Ultra Deep and MOSDEF CDFs are weighted by SFR. Limits are indicated by arrows at the bottom of the plot. Bottom panels: normalised histogram of the maximum distance between the BAT6 and the survey CDFs for each Monte Carlo realisation and of the p-value from the two-sample K–S test computed for each Monte Carlo realisation. The black curve represents the Gaussian kernel density estimation. The vertical dashed line indicates a p-value of 0.05, above which it is no longer possible to reject the null hypothesis that the two samples are drawn from the same distribution at a 95% confidence level.
