The stability of stellar disks in Milky-Way sized dark matter halos
Denis Yurin, Volker Springel
We employ an improved methodology to insert live stellar disks into high-resolution dark matter simulations of Milky Way sized halos, allowing us to investigate the fate of thin st…
Prograde and retrograde stars in nuclear cluster mergers. Evolution of the supermassive black hole binary and the host galactic nucleus
Alessandra Mastrobuono-Battisti, Pau Amaro Seoane, MÃ rius Josep Fullana i Alfonso +5
We address the orbital distribution of stars in merging nuclear star clusters (NSCs) and the subsequent effects on supermassive black hole binary (SMBHB) evolution. We ran direct-s…
Enhanced accretion rates of stars on Super-massive Black Holes by star-disk interactions in galactic nuclei
Andreas Just, Denis Yurin, Maxim Makukov +4
We investigate the dynamical interaction of a central star cluster surrounding a super-massive black hole and a central accretion disk. The dissipative force acting on stars in the…
An iterative method for the construction of N-body galaxy models in collisionless equilibrium
Denis Yurin, Volker Springel
(Abridged) We describe a new iterative approach for the realization of equilibrium N-body systems for given density distributions. Our method uses elements of Schwarzschild's techn…
Milky Way globular clusters on cosmological timescales. III. Interaction rates
Maryna Ishchenko, Margaryta Sobolenko, Peter Berczik +4
Aims. We carry out the self-consistent dynamic evolution of the orbital structure of Milky Way globular clusters. This allows us to estimate possible and probable close passages an…
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…
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…
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,…
