The spatially resolved view of star formation in galaxy clusters

TL;DR

This paper presents a detailed spatial analysis of star formation in galaxy clusters, linking local activity with global properties and examining the effects of environmental processes on galaxy evolution.

Contribution

It provides the first spatially resolved study connecting star formation patterns with gas phases and quenching histories in cluster galaxies using MUSE and multi-wavelength data.

Findings

Spatially resolved star formation correlates with global SFR-M* relation.

Jellyfish and post-starburst galaxies show distinct quenching signatures.

Star-forming clumps are observed in disks and stripped tails.

Abstract

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.
