"Dark" systems in globular clusters: GWs emission and limits on the formation of IMBHs
Manuel Arca-Sedda
Many observed globular clusters (GCs) seem to show a central overabundance of mass whose nature has not yet fully understood. Indeed, it is not clear whether it is due to a central…
Massive black holes interactions during the assembly of heavy sub-structures in the centre of galaxy clusters
M. Donnari, M. Arca-Sedda, M. Merafina
We performed a series of direct N-body simulations with the aim to follow the dynamical evolution of a galaxy cluster (GC) () in different environ…
Can dark energy explain the observed outflow in galaxy clusters?
M. Donnari, M. Arca-Sedda, M. Merafina
Recent observations of the Virgo cluster and the Local Group suggested that some galaxies are flowing out from their parent cluster. This may be the signature that dark energy (DE)…
Star clusters as tracers of galactic nuclei properties
Manuel Arca-Sedda, Roberto Capuzzo-Dolcetta
We present a series of -body simulations representing the evolution of a galactic nucleus and its stellar content in a nearly one-to-one representation. The aim of this suite of…
