We find that post-starburst galaxies at high-redshift ($z>1$) show high S\\'ersic indices, significantly higher than those of active star-forming galaxies, but with a distribution that is indistinguishable from the old quiescent population. We conclude that the morphological transformation occurs before (or during) the quenching of star formation. Recently quenched galaxies","authors_text":"Chris Simpson, David T. Maltby, James S.
