Globular Clusters in the Galactic Center Region: expected behavior in the infalling and merger scenario
Maria Gabriela Navarro, Roberto Capuzzo-Dolcetta, Manuel Arca-Sedda +1
The infall and merger scenario of massive clusters in the Milky Way's potential well, as one of the Milky Way formation mechanisms, is reexamined to understand how the stars of the…
Breaching the limit: formation of GW190521-like and IMBH mergers in young massive clusters
Manuel Arca Sedda, Francesco Paolo Rizzuto, Thorsten Naab +3
The LIGO-Virgo-Kagra collaboration (LVC) discovered recently GW190521, a gravitational wave (GW) source associated with the merger between two black holes (BHs) with mass M$_\…
Are we observing a NSC in course of formation in the NGC 4654 galaxy?
Riccardo Schiavi, Roberto Capuzzo-Dolcetta, Iskren Y. Georgiev +2
We use direct -body simulations to explore some possible scenarios for the future evolution of two massive clusters observed toward the center of NGC\,4654, a spiral galaxy with…
Future merger of the Milky Way with the Andromeda galaxy and the fate of their supermassive black holes
Riccardo Schiavi, Roberto Capuzzo-Dolcetta, Manuel Arca-Sedda +1
Our Galaxy and the nearby Andromeda galaxy (M31) are the most massive members of the Local Group, and they seem to be a bound pair, despite the uncertainties on the relative motion…
Stellar Black Hole Binary Mergers in Open Clusters
S. Rastello, P. Amaro-Seoane, M. Arca-Sedda +3
In this paper we study the evolution of a primordial black hole binary (BHB) in a sample of over 1500 direct-summation body simulations of small-and intermediate-size isolated…
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…
