Nuclear Star Clusters are observed at the center of many galaxies. In particular, in the Milky Way's center, the Nuclear Star Cluster coexists with a central supermassive black hole.

Abstract
Nuclear Star Clusters are observed at the center of many galaxies. In particular, in the Milky Way's center, the Nuclear Star Cluster coexists with a central supermassive black hole. The origin of these clusters is still unknown; a possible formation mechanism is the decay of massive globular clusters driven inward to the galactic center by dynamical friction and their subsequent merging. By investigating this scenario by means of sophisticated N-body simulations we found that this process could lead to a final product which actually shows many of the observed features of the Milky Way Nuclear Star Cluster.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
