Notes. The table lists the corresponding lookback time, stellar mass (M_⋆), effective radius measured using current radii ( $R_{eff}^{R}$ $\[\mathrm{R}_{\text {eff}}^{\mathrm{R}}\]$ ), effective radius measured using birth radii ( $R_{eff}^{R_{birth}}$ $\[\mathrm{R}_{\text {eff}}^{\mathrm{R}_{\text {birth}}}\]$ ) (see Section 4.1), SFR, and the metallicity gradient of the ISM at each redshift (see Section 3.3).

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
