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_{\…
Elusive Plunges and Heavy Intermediate-mass-ratio Inspirals from Single and Binary Supermassive Black Holes
Lazaros Souvaitzis, Antti Rantala, Thorsten Naab
The most massive galaxies in the Universe also host the largest supermassive black holes (SMBHs), with masses of and above. During their hierarchical a…
Massive Interacting Binaries Enhance Feedback in Star-Forming Regions
Claude Cournoyer-Cloutier, Eric P. Andersson, Sabrina M. Appel +9
We present a new framework to incorporate feedback from massive interacting binaries in simulations of star cluster formation. Our new feedback model adds binary stellar evolution…
FROST-CLUSTERS -- II. Massive stars, binaries and triples boost supermassive black hole seed formation in assembling star clusters
Antti Rantala, Natalia Lahén, Thorsten Naab +2
Observations and high-resolution hydrodynamical simulations indicate that massive star clusters form through a complex hierarchical assembly. We use simulations including post-Newt…
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…
Mergers all the way down: stellar collisions and kinematics of a dense hierarchically forming massive star cluster in a dwarf starburst
Natalia Lahén, Thorsten Naab, Antti Rantala +1
Recent observations indicate that the progenitors of globular clusters (GCs) at high redshifts had high average stellar surface densities above $10^5\, \mathrm{M}_\odot\, \mathrm{p…
