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…
The Noctua Suite of Simulations -- The Difficulty of Growing Massive Black Holes in Low-Mass Dwarf Galaxies
Jonathan Petersson, Michaela Hirschmann, Robin G. Tress +6
Aims. We study the individual and cumulative impact of stellar feedback processes on massive black hole (MBH) growth in a simulated low-mass dwarf galaxy. Methods. A suite of high-…
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…
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…
