Although galaxy clusters have proved to be wonderful laboratories for testing a plethora of modified gravity theories and other exotic alternatives to ΛCDM, until a few years ago, there was only one paper (from 1974), which obtained a limit on graviton mass (of $(10-29) eV) with clusters. To rectify this, in the last few years multiple works have obtained different bounds on graviton mass using single cluster data as well as stacking galaxy catalogs. We review these recent limits on graviton mass using galaxy clusters obtained using disparate methods. © 2020 Published under licence by IOP Publishing Ltd.
