The MEGaN project I. Missing formation of massive nuclear clusters and tidal disruption events by star clusters - massive black hole interactions
Manuel Arca-Sedda, Roberto Capuzzo-Dolcetta
We investigated the evolution of a massive galactic nucleus hosting a super-massive black hole (SMBH) with mass surrounded by a population o…
"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…
Dynamical Friction in Cuspidal Galaxies
M. Arca-Sedda, R. Capuzzo-Dolcetta
Dynamical friction is the process responsible for matter transport toward the inner regions of galaxies in form of massive objects, like intermediate mass black holes, globular clu…
