Globular clusters of the Gaia Enceladus/Sausage -- I. Orbital and dynamical evolution on cosmological timescales
Mykyta Bilodid, Maryna Ishchenko, Peter Berczik
We investigated Gaia-Enceladus/Sausage globular cluster samples and studied their orbital and dynamical evolution over cosmological timescales in external time-variable potential.…
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…
Gravitational influence of the globular cluster NGC 7078 (M 15) flyby of the Oort cloud system
M. Ishchenko, P. Berczik
Context. It is crucial to understand the interaction between globular clusters (GCs) and the Oort cloud, as close flybys of such massive objects can significantly disturb the cloud…
Dynamical evolution of the open clusters with different star formation efficiencies and orbital parameters
M. Ishchenko, V. Masliukh, M. Hradov +3
Open star clusters are dynamic systems whose evolution is critically influenced by initial conditions such as star formation efficiency and orbital parameters. Understanding their…
