Sample of galaxies with surviving CP cores (magenta) compared to the whole sample of ETGs (gray). Panels show redshift of the last major merger, fraction of recently formed in-situ stars Δinsitu, z ≤ 1, rotational support V/σ, and minor-to-major axis ratio q at 1Re as functions of stellar mass. Solid lines show the median profiles and shaded regions enclose the quartiles of the distributions. Galaxies with CP-cores had fewer recent major mergers, formed fewer in-situ stars after redshift z = 1, and are characterized by lower rotational support and rounder shapes than all ETGs of similar mass.

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.
