Dynamical evolution timescales for the supermassive black hole system in the galaxy NGC 7727 (Arp 222)
P. Berczik, M. Ishchenko, O. Veles +5
Context. A dual active galactic nucleus candidate with a separation of only 500 pc was recently found in NGC 7727. According to the hierarchical merging scenario, such objects woul…

Dynamical traction and black hole orbital migration
C. M. Boily, T. L. François, J. Freundlich +3
We investigate the circumstances which allow a black hole to remain put at the galactic centre when the stellar core is anisotropic. We use N-body calculations to study the respons…

Forming off-center massive black hole binaries in dwarf galaxies through Jacobi capture
Thibaut L. François, Christian M. Boily, Jonathan Freundlich +2
It is well established that black holes reside in the central regions of virtually all types of known galaxies. Recent observational and numerical studies however challenge this pi…
