Redshift evolution of Σ_SFR from z = 4 to 10. The median values and MAD of Σ_SFR in bins of increasing redshift are shown with black empty diamonds and black vertical error bars, while the best-fit to the bins is represented with a black dashed line with a gray region indicating its 1σ uncertainty. The best-fit obtained with the Bayesian linear regression is shown with a blue continuous line, with the blue dotted lines and the blue shaded regions representing the 1σ uncertainty and the ‘posterior plot’, respectively. Theoretical model predictions and comparison observations are included as specified in the legend.
