2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/395We investigate the behaviour of a cluster of young massive star clusters (hereafter super-cluster) in the tidal field of a host galaxy with a high-resolution particle-mesh code, Superbox. Specifically we want to establish if and how such super star-clusters merge and carry out a detailed study of the resulting merger-object. This merger-object shows either the properties of a compact spherical object or the elongated (`fluffy') shape of dSph-galaxies depending on the initial concentration of the super-cluster.6 pages, to appear in Massive Stellar Clusters, eds: A.
