Notes. Column (1): ALPINE source name. We only list the 12 sources with a S/N of the continuum > 4.5 (see Béthermin et al. 2020) that are considered in our analysis. The three sources classified in Béthermin et al. (2020) as multicomponent objects have not been considered. The ^(a) symbol indicates galaxies in common with the CRISTAL sample (Mitsuhashi et al. 2023). Column (2): spectroscopic redshift from the [CII] line emission. Column (3): dust continumm effective radius (see text for details). Column (4): [CII] line emission effective radius (Fujimoto et al. 2020). Column (5): rest-frame UV effective radius (Fujimoto et al. 2020). The ^(b) symbol indicates that the HST/F160W map has been considered, otherwise the radius from the HST/F814W maps have been reported. Columns (6) and (7): stellar mass and SFR (see text for details). Column (8): continuum S/N at 158 μm from Béthermin et al. (2020).

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.
