MAGICS II. Seed black holes stripped of their surrounding stars do not sink
Yihao Zhou, Diptajyoti Mukherjee, Nianyi Chen +7
MBH seed mergers are expected to be among the loudest sources of gravitational waves detected by the Laser Interferometer Space Antenna (LISA), providing a unique window into the b…
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 formation, evolution and disruption of star clusters with improved gravitational dynamics in simulated dwarf galaxies
Natalia Lahén, Antti Rantala, Thorsten Naab +3
So far, even the highest resolution galaxy formation simulations with gravitational softening have failed to reproduce realistic life cycles of star clusters. We present the first…
The importance of nuclear star clusters for massive black hole growth and nuclear star formation in simulated low-mass galaxies
Christian Partmann, Thorsten Naab, Natalia Lahén +5
Observed low-mass galaxies with nuclear star clusters (NSCs) can host accreting massive black holes (MBH). We present simulations of dwarf galaxies ($M_{\mathrm{baryon}} \sim 0.6 -…
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…
Close Encounters of Wide Binaries Induced by the Galactic Tide: Implications for Stellar Mergers and Gravitational-Wave Sources
Jakob Stegmann, Alejandro Vigna-Gómez, Antti Rantala +6
A substantial fraction of stars can be found in wide binaries with projected separations between and . In the standard lore of binary physics, these would…
A calibrated model for N-body dynamical friction acting on supermassive black holes
Anna Genina, Volker Springel, Antti Rantala
Black holes are believed to be crucial in regulating star formation in massive galaxies, which makes it essential to faithfully represent the physics of these objects in cosmologic…
FROST-CLUSTERS -- I. Hierarchical star cluster assembly boosts intermediate-mass black hole formation
Antti Rantala, Thorsten Naab, Natalia Lahén
Observations and high-resolution hydrodynamical simulations indicate that massive star clusters assemble hierarchically from sub-clusters with a universal power-law cluster mass fu…
