dc.description.abstractThe detection of extremely massive clusters at z > 1 such as SPT-CLJ0546-5345, SPT-CLJ2106-5844 and XMMUJ2235.3-2557 has been considered by some authors as a challenge to the standard Λ cold dark matter cosmology. In fact, assuming Gaussian initial conditions, the theoretical expectation of detecting such objects is as low as ≤1 per cent. In this paper we discuss the probability of the existence of such objects in the light of the vector dark energy paradigm, showing by means of a series of N-body simulations that chances of detection are substantially enhanced in this non-standard frameworken_US
