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 (…

Is the overconcentration of pristine populations in Galactic globular clusters real? An N-body approach to the problem

P. Berczik, O. Sobodar, F. Flammini Dotti +5

Recent observations indicate that in some Milky Way globular clusters (GCs) pristine red giant branch (RGB) stars appear more centrally concentrated than enriched ones. This contra…

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…

Dynamical evolution timescales for the supermassive black hole system in the galaxy NGC 7727 (Arp 222)

P. Berczik, M. Ishchenko, O. Veles +5

Context. A dual active galactic nucleus candidate with a separation of only 500 pc was recently found in NGC 7727. According to the hierarchical merging scenario, such objects woul…
