RABBITS -- I. The crucial role of nuclear star formation in driving the coalescence of supermassive black hole binaries

Shihong Liao, Dimitrios Irodotou, Peter H. Johansson +5

In this study of the `Resolving supermAssive Black hole Binaries In galacTic hydrodynamical Simulations' (RABBITS) series, we focus on the hardening and coalescing process of super…

RABBITS -- II. The impact of AGN feedback on coalescing supermassive black holes in disc and elliptical galaxy mergers

Shihong Liao, Dimitrios Irodotou, Peter H. Johansson +5

In this study of the `Resolving supermAssive Black hole Binaries In galacTic hydrodynamical Simulations' (RABBITS) series, we investigate the orbital evolution of supermassive blac…

Growth of Seed Black Holes in Galactic Nuclei

Rainer Spurzem, Francesco Rizzuto, Manuel Arca Sedda +5

The evolution of dense star clusters is followed by direct high-accuracy N-body simulation. The problem is to first order a gravitational N-body problem, but stars evolve due to as…

The Dragon-II simulations -- II. Formation mechanisms, mass, and spin of intermediate-mass black holes in star clusters with up to 1 million stars

Manuel Arca Sedda, Albrecht W. H. Kamlah, Rainer Spurzem +4

The processes that govern the formation of intermediate-mass black holes (IMBHs) in dense stellar clusters are still unclear. Here, we discuss the role of stellar mergers, star-BH…

The growth of intermediate mass black holes through tidal captures and tidal disruption events

Francesco Paolo Rizzuto, Thorsten Naab, Antti Rantala +5

We present simulations, including post-Newtonian dynamics, of dense clusters of low-mass stars harbouring central black holes (BHs) with initial masses of 50, 30…

Modelling the accretion and feedback of supermassive black hole binaries in gas-rich galaxy mergers

Shihong Liao, Peter H. Johansson, Matias Mannerkoski +6

We introduce a new model for the accretion and feedback of supermassive black hole (SMBH) binaries to the KETJU code, which enables us to resolve the evolution of SMBH binaries dow…

The complex evolution of supermassive black holes in cosmological simulations

Peter H. Johansson, Matias Mannerkoski, Antti Rantala +4

We present here self-consistent zoom-in simulations of massive galaxies forming in a full cosmological setting. The simulations are run with an updated version of the KETJU code, w…

The two phases of core formation -- orbital evolution in the centres of ellipticals with supermassive black hole binaries

Matteo Frigo, Thorsten Naab, Antti Rantala +4

The flat stellar density cores of massive elliptical galaxies form rapidly due to sinking supermassive black holes (SMBH) in gas-poor galaxy mergers. After the SMBHs form a bound b…

Black hole mergers in compact star clusters and massive black hole formation beyond the mass-gap

Francesco Paolo Rizzuto, Thorsten Naab, Rainer Spurzem +4

We present direct N-body simulations, carried out with Nbody6++GPU, of young and compact low metallicity star clusters with stars, a velocity dispersion of …

Intermediate Mass Black Hole Formation in compact Young Massive Star Clusters

Francesco Paolo Rizzuto, Thorsten Naab, Rainer Spurzem +6

Young dense massive star clusters are a promising environment for the formation of intermediate mass black holes (IMBHs) through collisions. We present a set of 80 simulations carr…
