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…
Apparent counter-rotation in the torus of NGC 1068: influence of an asymmetric wind
Elena Yu. Bannikova, Nina A. Akerman, Massimo Capaccioli +3
The recent ALMA maps together with observations of HO maser emission seem to suggest the presence of a counter-rotation in the obscuring torus of NGC 1068. We propose to explai…
Dynamical evolution modeling of the Collinder 135 & UBC 7 binary star cluster
Marina Ishchenko, Peter Berczik, Nina Kharchenko
The purpose of the present work is a detailed investigation of the dynamical evolutionof Collinder 135 and UBC 7 star clusters. We present a set of dynamical numerical simulationsu…
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…
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…
Extreme kinematic misalignment in IllustrisTNG galaxies: the origin, structure and internal dynamics of galaxies with a large-scale counterrotation
Sergey Khoperskov, Igor Zinchenko, Branislav Avramov +9
Modern galaxy formation theory suggests that the misalignment between stellar and gaseous components usually results from an external gas accretion and/or interaction with other ga…
Cosmological Insights into the Early Accretion of \textit{r}-Process-Enhanced stars. I. A Comprehensive Chemo-dynamical Analysis of LAMOST J1109+0754
Mohammad K. Mardini, Vinicius M. Placco, Yohai Meiron +10
This study presents a comprehensive chemo-dynamical analysis of LAMOST J1109+0754, a bright (V = 12.8), extremely metal-poor (\abund{Fe}{H} = ) star, with a strong \textit{r…
Collinder 135 and UBC 7: A Physical Pair of Open Clusters
Dana Kovaleva, Marina Ishchenko, Ekaterina Postnikova +7
Given the closeness of the two open clusters Cr 135 and UBC 7 on the sky, we investigate the possibility of the two clusters to be physically related. We aim to recover the present…
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…
