The RCS 2319+00 supercluster is a massive supercluster at z = 0.9 comprising three optically selected, spectroscopically confirmed clusters separated by < 3 Mpc on the plane of the sky. This supercluster is one of a few known examples of the progenitors of present-day massive clusters (10^15 solar masses by z ∼ 0.5). RCS 2319+00 therefore allows us to witness the hierarchical buildup of large-scale structure in the Universe.We present an extensive multiwavelength study carried out on the supercluster field. A spectroscopic campaign resulted in 302 structure members spanning three distinct redshift walls separated by ∼ 65 Mpc. We find evidence of substructure in the supercluster field, with a friends-of-friends (FOF) analysis identifying fi...
