Fig. 2.


Stellar mass cumulative distributions in the matched samples (dotted grey curves) for the red, green, and blue galaxies from top to bottom. The stellar mass distributions in the flux-limited samples (solid black curves) and that of the [NeV] emitters (extracted from the matched samples and shown with dashed curves, colour-coded accordingly) are also shown together with their median values (vertical lines and same style as before). The error bars plotted at the top of the vertical lines represent the median standard deviation of parent and [NeV] distributions. The Kolmogorov–Smirnov test (probability and distance quoted in each panel) confirms as statistically significant the difference between stellar mass distributions of [NeV] emitters and their parent matched samples in the blue cloud (but not in the green and red sub-samples). The blue [NeV] emitters are significantly more massive than the red [NeV] emitters (cf. dashed curves in the top and bottom panels).

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.
