Context. Galaxies in overdense environments, such as clusters, present predominantly quenched populations up to z∼1. This suggests that environmental mechanisms suppress the star formation in these galaxies for the majority of cosmic history. At low redshifts, galaxies in rich group and cluster environments frequently show a radio emission excess in the IR-radio correlation, but this has yet to be confirmed at high redshifts, when environmental effects begin to strongly affect the evolution of cluster galaxies. Aims. We investigate the effect of the environment on the infrared and radio emission of cluster galaxies during the transition epoch at 11 Mpc). We find no difference in the IR-radio correlation between galaxies that host AGNs and non-active star-forming galaxies either. This suggests that our AGNs are overwhelmingly radio quiet and therefore do not affect the results we described above. We conclude that further investigations based on larger datasets are needed to constrain the impact of the cluster environment on the IR-radio correlation better.
