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…
