The difficult path to coalescence: massive black hole dynamics in merging low mass dark matter haloes and galaxies

Christian Partmann, Thorsten Naab, Antti Rantala +3

We present a high resolution numerical study of the sinking and merging of massive black holes (MBHs) with masses in the range of in multiple mino…

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…

Signatures of the Many Supermassive Black Hole Mergers in a Cosmologically Forming Massive Early-Type Galaxy

Matias Mannerkoski, Peter H. Johansson, Antti Rantala +3

We model here the merger histories of the supermassive black hole (SMBH) population in the late stages of a cosmological simulation of a galaxy grou…

Resolving the Complex Evolution of a Supermassive Black Hole Triplet in a Cosmological Simulation

Matias Mannerkoski, Peter H. Johansson, Antti Rantala +2

We present here a self-consistent cosmological zoom-in simulation of a triple supermassive black hole (SMBH) system forming in a complex multiple galaxy merger. The simulation is r…

Gravitational Waves from the Inspiral of Supermassive Black Holes in Galactic-scale Simulations

Matias Mannerkoski, Peter H. Johansson, Pauli Pihajoki +2

We study the orbital evolution and gravitational wave (GW) emission of supermassive black hole (SMBH) binaries formed in gas-free mergers of massive early-type galaxies using the h…
