N2 - • I have discussed testing gravity theory using cluster's observations of the gas and shear profiles simultaneously. • The gas distributions depend on the gravitational potential, while the shear profile depends on the lens potential, which are complimentary to put a constraint. • Using the observations of the gas and shear profiles of the Coma cluster, I put a constraint on the generalized Galileon model. (µG, µL) • 2 parameters are constrained at the same time. • The constraint on the original Galileon model is marginal.
