Abstract

Using multiwavelength observations of the Coma cluster, we obtained the following 3 results. 1. The hydrostatic equilibrium approximately holds in the outer region of the Coma cluster. 2. Presence of chameleon force requires the estimation of low hydrostatic mass. 3. Comparing theoretical model with multiwavelengs observations gave us useful constraint on the chameleon gravity model parameters. For an f(R) model, \fR0\^ 0.5
