Identifying supermassive black hole recoil in elliptical galaxies
Alexander Rawlings, Atte Keitaanranta, Max Mattero +8
We study stellar core growth in simulations of merging massive () elliptical galaxies by a supermassive black hole (SMBH) displaced by gravitatio…
The supermassive black hole merger driven evolution of high-redshift red nuggets into present-day cored early-type galaxies
Antti Rantala, Alexander Rawlings, Thorsten Naab +2
Very compact ( kpc) massive quiescent galaxies (red nuggets) are more abundant in the high-redshift Universe (-) than today. Their size evolution…
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…
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…
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…
KETJU -- resolving small-scale supermassive black hole dynamics in GADGET-4
Matias Mannerkoski, Alexander Rawlings, Peter H. Johansson +5
We present the new public version of the KETJU supermassive black hole (SMBH) dynamics module, as implemented into GADGET-4. KETJU adds a small region around each SMBH where the dy…
