The effect of triaxial galaxy shapes on the dynamics of triple supermassive black holes in a cosmological context
Navonil Saha, Margarita Sobolenko, Peter Berczik +2
The hierarchical nature of galaxy formation in the Lambda cold dark matter (CDM) cosmological framework model often leads to the presence of multiple supermassive black holes (…
Rapid formation of a very massive star >50000 and subsequently an IMBH from runaway collisions. Direct N-body and Monte Carlo simulations of dense star clusters
Marcelo C. Vergara, Abbas Askar, Albrecht W. H. Kamlah +15
Context. We present simulations of a massive young star cluster using \textsc{Nbody6++GPU} and \textsc{MOCCA}. The cluster is initially more compact than previously published model…
Dynamical evolution of massless particles in star clusters with NBODY6++GPU-MASSLESS: II. The long-term evolution of free-floating comets
Francesco Flammini Dotti, M. B. N. Kouwenhoven, Kai Wu +5
Context. Comets, asteroids, planetesimals, free-floating planets and brown dwarfs, are continuously injected into the intra-cluster environment after expulsion from their host plan…
Intermediate Mass Black Hole Binary Evolution in Nuclear Star Clusters: the effect of the stellar mass black hole population
Fazeel Mahmood Khan, Peter Berczik, Margarita Sobolenko +4
In this study, we investigate the dynamics of Intermediate-Mass Black Hole (IMBH) binaries within Nuclear Star Clusters (NSCs) that contain a population of stellar-mass black holes…
The effect of triaxiality on the dynamics of triple supermassive black holes in a cosmological context
Navonil Saha, Peter Berczik, Andreas Just +1
The hierarchical nature of galaxy formation in the CDM framework often leads to multiple supermassive black holes (SMBHs) in the galactic nuclei. The timescale over which galax…
Evolution of star clusters with initial bulk rotation via N-body simulations
Abylay Bissekenov, Xiaoying Pang, Albrecht Kamlah +6
Young star clusters can inherit bulk rotation from the molecular clouds from which they have formed. This rotation can affect the long-term evolution of a star cluster and its cons…
