Abstract

The maximum size of a bound cosmic structure is computed perturbatively as a function of its mass in the framework of the cubic galileon, proposed recently to model the dark energy of our Universe. Comparison of our results with observations constrains the matter-galileon coupling of the model to 0.033α0.170.033\lesssim \alpha \lesssim 0.17, thus improving previous bounds based solely on solar system physics.
