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…
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…
SMART: A new implementation of Schwarzschild's Orbit Superposition technique for triaxial galaxies and its application to an N-body merger simulation
Bianca Neureiter, Jens Thomas, Roberto Saglia +6
We present SMART, a new 3D implementation of the Schwarzschild Method and its application to a triaxial N-body merger simulation. SMART fits full line-of-sight velocity distributio…
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…
The simultaneous formation of cored, tangentially biased, and kinematically decoupled centers in massive early-type galaxies
Antti Rantala, Peter H. Johansson, Thorsten Naab +2
We study the impact of merging supermassive black holes (SMBHs) on the central regions of massive early-type galaxies (ETGs) using a series of merger simulations with varying mass…
The formation of extremely diffuse galaxy cores by merging supermassive black holes
Antti Rantala, Peter H. Johansson, Thorsten Naab +2
Given its velocity dispersion, the early-type galaxy NGC 1600 has an unusually massive () central supermassive black hole (SMBH), surrounded…
