Abstract [en]

In this paper, analytical solutions describing static and spherically symmetric sources in the decoupling limit of massive gravity are derived. We analyze the model parameter range and specify when a Vainshtein mechanism is possible. Furthermore, we use gravitational lensing and velocity dispersion data from galaxies to put constraints on the mass scale of the graviton. The result for the inverse graviton mass scale lambda(g) = h/(cm(g)), in units of the Hubble radius r(H) = c/H-0, is of the order lambda(g)/r(H) greater than or similar to 0.01 - 0.02 at 95% confidence level.
