抄録

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.
