Stellar discs and intermediate-mass black holes in galactic nuclei II. Fragmenting the disc and forming the S-stars in a live nuclear star cluster
Taras Panamarev, Bence Kocsis
We present direct -body simulations of a stellar disc around the supermassive black hole Sgr~A*, perturbed by an intermediate-mass black hole (IMBH) and embedded in a live nucle…
Simulating tidal disruption events in nuclear star clusters
Philip Cho, Kai Wu, Francesco Flammini Dotti +5
Context. Nuclear star clusters (NSCs) and supermassive black holes (SMBHs) often coexist at the centers of galaxies, engaging in complex dynamical interactions that influence SMBH…
Stellar discs and intermediate-mass black holes in galactic nuclei I. Fragmenting the disc in an isotropic stellar potential
Taras Panamarev, Xiang Zou, Bence Kocsis
The origin of the complex orbital structure of young massive stars at the Galactic centre remains an open question. If these stars formed in a single episode from a gaseous accreti…
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…
Modeling Tidal Disruption Events and Compact Object Plunges in Nuclear Star Clusters
Philip Cho, Kai Wu, Francesco Flammini Dotti +2
We study tidal disruption events (TDEs) and compact object inspirals in nuclear star clusters (NSCs) hosting a central supermassive black hole (SMBH), focusing on their role in SMB…
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…
