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…
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…
The challenge of simulating the star cluster population of dwarf galaxies with resolved interstellar medium
Jessica M. Hislop, Thorsten Naab, Ulrich P. Steinwandel +4
We present results on the star cluster properties from a series of high resolution smoothed particles hydrodynamics (SPH) simulations of isolated dwarf galaxies as part of the GRIF…
The SIBELIUS Project: E Pluribus Unum
Till Sawala, Stuart McAlpine, Jens Jasche +4
We introduce "Simulations Beyond The Local Universe" (SIBELIUS) that connect the Local Group to its cosmic environment. We show that introducing hierarchical small-scale perturbati…
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…
