Investigating the formation channel of GW231123: Population III stars or hierarchical mergers?
Federico Angeloni, Konstantinos Kritos, Raffaella Schneider +5
The gravitational wave event GW231123, with component black hole masses lying within or above the pair-instability mass gap, poses a significant challenge to current stellar evolut…
Direct N-body simulations of rotating and extremely massive Population III star clusters
Kai Wu, Ataru Tanikawa, Francesco Flammini Dotti +6
Aims. We present eight direct N-body simulations with NBODY6++GPU of extremely massive, initially rotating Population III star clusters with 1.01 x 10^5 stars. Methods. Our models…
Rapid formation of a very massive star >50000 and subsequently an IMBH from runaway collisions. Direct N-body and Monte Carlo simulations of dense star clusters
Marcelo C. Vergara, Abbas Askar, Albrecht W. H. Kamlah +15
Context. We present simulations of a massive young star cluster using \textsc{Nbody6++GPU} and \textsc{MOCCA}. The cluster is initially more compact than previously published model…
Gravitational Wave Astronomy With TianQin
En-Kun Li, Shuai Liu, Alejandro Torres-Orjuela +50
The opening of the gravitational wave window has significantly enhanced our capacity to explore the universe's most extreme and dynamic sector. In the mHz frequency range, a divers…
Simulations predict intermediate-mass black hole formation in globular clusters
Michiko S. Fujii, Long Wang, Ataru Tanikawa +2
Intermediate-mass black holes (IMBHs) are those between 100 and 10 solar masses (); their formation process is debated. One possible origin is the growth of less mas…
Merging Hierarchical Triple Black Hole Systems with Intermediate-mass Black Holes in Population III Star Clusters
Shuai Liu, Long Wang, Yi-Ming Hu +2
Theoretical predictions suggest that very massive stars have the potential to form through multiple collisions and eventually evolve into intermediate-mass black holes (IMBHs) with…
