Dynamical evolution of Milky Way globular clusters on the cosmological timescale I. Mass loss and interaction with the nuclear star cluster
M. Ishchenko, P. Berczik, T. Panamarev +7
Context. Based on the Gaia DR3, we reconstructed the orbital evolution of the known Milky Way globular clusters and found that six objects, NGC 6681, NGC 6981, Palomar 6, NGC 6642,…
Milky Way globular clusters on cosmological timescales. III. Interaction rates
Maryna Ishchenko, Margaryta Sobolenko, Peter Berczik +4
Aims. We carry out the self-consistent dynamic evolution of the orbital structure of Milky Way globular clusters. This allows us to estimate possible and probable close passages an…
Milky Way globular clusters on cosmological timescales. II. Interaction with the Galactic centre
Maryna Ishchenko, Margaryta Sobolenko, Dana Kuvatova +2
Aims. We estimate the dynamical evolution of the Globular Clusters interaction with the Galactic centre that dynamically changed in the past. Methods. We simulated the orbits of 14…
Kinematic characteristics of the Milky Way globular clusters based on Gaia DR2 data
I. V. Chemerynska, M. V. Ishchenko, M. O. Sobolenko +2
Using the data from Gaia (ESA) Data Release 2 we performed the orbital calculations of globular clusters (GCs) of the Milky Way. To explore possible close encounters (or collisions…
Merging of unequal mass binary black holes in non-axisymmetric galactic nuclei
Peter Berczik, Manuel Arca Sedda, Margaryta Sobolenko +3
In this work, we study the stellar-dynamical hardening of unequal mass supermassive black hole (SMBH) binaries in the central regions of merging galactic nuclei. We present a compr…
Supermassive black holes coalescence mediated by massive perturbers: implications for gravitational waves emission and nuclear cluster formation
Manuel Arca Sedda, Peter Berczik, Roberto Capuzzo-Dolcetta +3
A large fraction of galactic nuclei is expected to host supermassive black hole binaries (BHB), likely formed during the early phase of galaxies assembly and merging. In this paper…
