FAIR-Compliant Architecture for Heterogeneous Astronomical Data: KazVO Framework
Ildana Izmailova, Denis Yurin, Yerlan Aimuratov +17
This paper presents the architecture of the Kazakhstani National Virtual Observatory (KazVO) - an International Virtual Observatory Alliance (IVOA) compliant node that unifies the…
Dynamical evolution of Milky Way globular clusters on the cosmological timescale II. Terzan 2, 4, and 5 mass loss and collision tracking
M. Ishchenko, P. Berczik, D. Kuvatova
We investigate the long-term dynamical evolution of Ter2, Ter4, and Ter5, focusing on their mutual interactions, mass-loss behaviour, and survivability in the dense Galactic centre…
The background gas humming and multi-messenger transients of stalled supermassive black hole binaries
Pau Amaro Seoane, Alessandra Mastrobuono Battisti, Chingis Omarov +5
We establish the multi-messenger mechanics of episodic mass transfer in supermassive black hole binaries stalled within circumbinary discs. Utilizing continuous wavelet transforms,…
The contribution to Galactic Centre γ-ray excess from cluster-born millisecond pulsars. Constraints from direct N-body simulations
M. Kalambay, M. Ishchenko, D. Kuvatova +2
The Galactic Centre γ-ray excess (GCE), observed by Fermi-LAT around Sgr A*, exceeds expectations from standard cosmic-ray models and is commonly attributed either to dark matter a…
How our proto-nuclear star cluster formed and grew due to early globular cluster disruption. I. Case of low masses
D. Kuvatova, M. Ishchenko, P. Berczik +3
We investigate the accretion of globular cluster stars on early cosmological timescales through detailed N-body simulations of theoretical GC models to assess the role of this mech…
Taming the plunge: A circularization trap of supermassive black hole binaries
Pau Amaro Seoane, Alessandra Mastrobuono Battisti, Chingis Omarov +5
We investigate the orbital eccentricity evolution of supermassive black hole binaries within galactic environments. We analyze the dynamics in triaxial merger remnants and subseque…
Estimating Gamma-Ray Flux from Millisecond Pulsars Originating in Globular Clusters Near the Galactic Center
Dana Kuvatova, Taras Panamarev, Maryna Ishchenko +2
In this study, we investigate the contribution of millisecond pulsars (MSPs) to the gamma-ray excess observed in the Galactic Center by analyzing data from high-resolution direct N…
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. 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…
Intermediate-mass ratio inspirals in merging elliptical galaxies
Verónica Vázquez-Aceves, Pau Amaro Seoane, Dana Kuvatova +3
Close encounters between two initially unbound objects can result in a binary system if enough energy is released as gravitational waves (GWs). We address the scenario in which suc…
