Dark Energy and the mass of galaxy clusters
Abstract
Up to now, Dark Energy evidences are based on the dynamics of the universe on very large scales, above 1 Gpc. Assuming it continues to behave like a cosmological constant on much smaller scales, I discuss its effects on the motion of non-relativistic test-particles in a weak gravitational field and I propose a way to detect evidences of ≠ 0 at the scale of about 1 Mpc: the main ingredient is the measurement of galaxy cluster masses.
