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 (S…
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 galaxi…
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…
Dynamical evolution timescales for the triple supermassive black hole system in NGC 6240
P. Berczik, M. Sobolenko, M. Ishchenko
Based on the available observational data from the literature, we analysed the dynamics of the NGC 6240 galaxy central supermassive black hole (SMBH) system. For the dynamical mode…
Milky Way globular clusters on cosmological timescales. IV. Guests in the outer Solar System
Maryna Ishchenko, Peter Berczik, Margarita Sobolenko
The present epoch of the Gaia success gives us a possibility to predict the dynamical evolution of our Solar System in the global Galactic framework with high precision. We statist…
Milky Way globular clusters on cosmological timescales. I. Evolution of the orbital parameters in time-varying potentials
M. Ishchenko, M. Sobolenko, P. Berczik +4
Context. Recent observational data show that the Milky Way (MW) galaxy contains about 170 globular clusters (GCs). A fraction of them is likely formed in dwarf galaxies accreted on…
Statistical Analysis of the Probability of Interaction of Globular Clusters with Each Other and with the Galactic Center on the Cosmological Time Scale According to Gaia DR2 Data
Maryna Ishchenko, Margaryta Sobolenko, Peter Berczik +1
This study is aimed at investigating the dynamic evolution of the orbits of stellar globular clusters (GCs). To integrate the orbits backward in time, the authors use models of the…
NGC 6240 Supermassive Black Hole Binary dynamical evolution based on Chandra data
M. Sobolenko, O. Kompaniiets, P. Berczik +4
The main idea of our research is to estimate the physical coalescence time of the double supermassive black hole (SMBH) system in the centre of NGC 6240 based on the X-ray observat…
Merging timescale for supermassive black hole binary in interacting galaxy NGC 6240
Margarita Sobolenko, Peter Berczik, Rainer Spurzem
One of the main possible way of creating the supermassive black hole (SMBH) is a so call hierarchical merging scenario. Central SMBHs at the final phase of interacting and coalesci…
The bound mass of Dehnen models with centrally peaked star formation efficiency
B. Shukirgaliyev, A. Otebay, M. Sobolenko +12
Understanding the formation of star clusters with low star-formation efficiency (SFE) is very important to know about the star-formation history. In N-body models of star cluster e…
