The XXL survey. XLIX. Linking the members star formation histories to the cluster mass assembly in the z=1.98 galaxy cluster XLSSC 122

The most massive protoclusters virialize to become clusters at z\sim 2, which is also a critical epoch for the evolution of their member galaxies. XLSSC 122 is a z=1.98 galaxy cluster with 37 spectroscopically confirmed members. We aim to characterize their star formation histories and to put them in the... Show more
