The role of galaxy cluster in the mass-metallicity relation

Evolution of the MZR at z~0.3 with   star forming galaxies in the AC114 galaxy cluster. The mass-metallicity relation (MZR) and its evolution is understood very well. However, the construction of this correlation is generally done with field galaxies. Therefore the physical processes studied involve only the intrinsic properties of galaxies. In this work, we study the evolution of the MZR  by using star-forming galaxies of the AC114 galaxy cluster located at z~0.3. We study the role of galaxy clusters in the MZR. We found a change in the slope of the MZR with respect to the constructed with field galaxies at the same redshift. This feature can be the result of the quench of the star-formation rates when galaxies interact with the intra-cluster medium.
