Median radial profiles and 68th percentile spread of stellar ages at z = 0. Before extracting the running median and scatter, we calculated the mean stellar ages for each galaxy in nine equal-width radial bins between 0 and 5 R1/2. The solid lines and shaded regions correspond to the statistics of the class indicated at the top of each panel. The dashed lines are the running medians from the panels to the left of each panel for a direct comparison. Higher values correspond to an older population, which is fairly constant at around ten gigayears for early-quenched galaxies. Main-sequence-type galaxies show increasingly young populations toward the center, while the three types of rejuvenating classes are the youngest at roughly one half-mass radius and increase in age again toward the very center as well as the outskirts.

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.
