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…
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…
