RABBITS IV: Stellar feedback and SMBH merging time-scales in the sub-Milky Way mass regime
Ruby J. Wright, Roosa Heiskanen, Shihong Liao +5
Merging supermassive black holes (SMBHs) in low- and intermediate-mass galaxies are important sources for future millihertz gravitational-wave observatories such as LISA. Predictin…
The LISA Astrophysics MBHcatalogues Project: A comparison of predictions of simulated massive black hole binaries
David Izquierdo-Villalba, Melanie Habouzit, Matteo Bonetti +67
In the hierarchical paradigm of galaxy formation, central massive black holes (MBHs) are expected to coalesce after the merger of their host galaxies. One of the main goals of the…
RABBITS - III. Modelling relativistic accretion discs around spinning black holes in galaxy formation simulations
Dimitrios Irodotou, Shihong Liao, Theodoros Nakas +6
In this third study of the 'Resolving supermAssive Black hole Binaries In galacTic hydrodynamical Simulations' (RABBITS) series we develop and implement a geometrically thin relati…
Rapid sinking and efficient mergers of supermassive black holes in compact high-redshift galaxies
Atte Keitaanranta, Peter H. Johansson, Alexander Rawlings +5
We present a cosmological zoom-in simulation targeting the high redshift compact progenitor phase of massive galaxies, with the most massive galaxy reaching a stellar mass of $M_{\…
Stellar Cores Live Long and Prosper in Cuspy Dark Matter Halos
Jenni Häkkinen, Alexander Rawlings, Till Sawala +1
The existence of cuspy or cored centers of dark matter halos is a crucial discriminant between different dark matter models. It has recently been claimed based on dynamical argumen…
Caught in the act: detections of recoiling supermassive black holes from simulations
Alexander Rawlings, Peter H. Johansson, Thorsten Naab +3
We study the detectability of supermassive black holes (SMBHs) with masses of displaced by gravitational wave recoil kicks $(v_{\rm ki…
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…
Apocalypse When? No Certainty of a Milky Way -- Andromeda Collision
Till Sawala, Jehanne Delhomelle, Alis J. Deason +5
It is commonly believed that our own Milky Way is on a collision course with the neighbouring Andromeda galaxy. As a result of their merger, predicted in around five billion years,…
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…
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…
Reviving stochasticity: uncertainty in SMBH binary eccentricity is unavoidable
Alexander Rawlings, Matias Mannerkoski, Peter H. Johansson +1
We study supermassive black hole (SMBH) binary eccentricity of equal-mass galaxy mergers in -body simulations with the KETJU code, which combines the GAGDET-4 fast multipole gra…
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…
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…
