Fig. 4.


Top: absolute numbers of [NeV] emitters within the green valley, computed in four equally-populated intervals of the (rK) colour. Error bars represent the Poissonian uncertainty. Bottom: fractions of [NeV] emitters among the red sequence (red circles), green valley (green stars) and blue cloud (blue squares) galaxy populations. Error bars on the blue and red points are computed using the resampling technique. The fraction of [NeV] emitters in the green valley is preferentially higher in galaxies with bluer (rK) colours.

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.
