The evolution of the colour-magnitude relation and of the star formation activity in galaxy clusters since z~0.8
We present recent results on the evolution of the colour-magnitude relation
and of the star formation activity in galaxy clusters since z~0.8. Results are
based on the ESO Distant Cluster Survey (EDisCS) - an ESO large programme aimed
at the study of cluster structure and cluster galaxy evolution over a
significant fraction of cosmic time - and are discussed in the framework of the
current standard paradigm of structure formation.Comment: 8 pages, 5 figure, to appear in ASP Conference Series (Proceedings of

The spatially resolved view of star formation in galaxy clusters
Integral field spectroscopic studies of galaxies in dense environments, such
as clusters and groups of galaxies, have provided new insights for
understanding how star formation proceeds, and quenches. I present the
spatially resolved view of the star formation activity and its link with the
multiphase gas in cluster galaxies based on MUSE and multi-wavelength data of
the GASP survey. I discuss the link among the different scales (i.e. the link
between the spatially resolved and the global star formation rate-stellar mass
relation), the spatially resolved signatures and the quenching histories of
jellyfish (progenitors) and post-starburst (descendants) galaxies in clusters.
Finally, I discuss the multi-wavelength view of star-forming clumps both in
galaxy disks and in the tails of stripped gas.Comment: 10 pages, 8 figures, proceedings of IAUS373: Resolving the rise and
