The dearth of nuclear star clusters in bright galaxies
Manuel Arca-Sedda, Roberto Capuzzo-Dolcetta, Mario Spera
We investigate the interaction of a massive globular cluster (GC) with a super massive black hole (SMBH), located at the centre of its host galaxy, by means of direct N-body simula…
On the formation of compact, massive sub-systems in stellar clusters and its relation with intermediate mass black holes
Manuel Arca-Sedda
During their evolution, star clusters undergo mass segregation, by which the orbits of the most massive stars shrink, while the lighter stars move outwards from the cluster centre.…
The interaction between supermassive black holes and globular clusters
Mario Spera, Manuel Arca-Sedda, Roberto Capuzzo-Dolcetta
Almost all galaxies along the Hubble sequence host a compact massive object (CMO) in their center. The CMO can be either a supermassive black hole (SMBH) or a very dense stellar cl…
Henize 2-10: the ongoing formation of a nuclear star cluster around a massive black hole
Manuel Arca-Sedda, Roberto Capuzzo-Dolcetta, Fabio Antonini +1
The central region of the galaxy Henize 2-10 has a central black hole (BH) with a mass of about M. While this black hole does not appear to coincide with any…
