Recent bounds on graviton mass using galaxy clusters
  Although galaxy clusters have proved to be wonderful laboratories for testing
a plethora of modified gravity theories and other exotic alternatives to
$\Lambda$CDM, until a few years ago, there was only one paper (from 1974),
which obtained a limit on graviton mass of $\mathcal{O}(10^{-29})$ 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.
