Stellar ages estimated with CIGALE. Upper panel: ages of the (oldest) stellar population for free-age models as a function of redshift. Black triangles: two-populations model, green circles: decl.-τ model, magenta crosses: rising-τ model. The red steps correspond to the age adopted for the models with fixed ages. Lower panel: mass weighted ages for all the models: same symbols as in the upper panel are used for the free-age models, blue squares and red diamonds are added for the fixed-age rising-τ model and two-populations models, respectively. The curves correspond to the age at redshift z for a redshift formation zf = 8 (thick line), zf = 5 (thin line), and zf = 2.5 (dotted line).
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.
