On the Formation of GW231123 in Population III Star Clusters
Shuai Liu, Long Wang, Ataru Tanikawa +2
GW231123 is a binary black hole merger whose primary component lies within or above the pair-instability mass gap, while the secondary component falls within this gap. The standard…

Pair-Instability Gap Black Holes in Population III Star Clusters: Pathways, Dynamics, and Gravitational Wave Implications
Weiwei Wu, Long Wang, Shuai Liu +3
The detection of the gravitational wave (GW) event GW190521 raises questions about the formation of black holes within the pair-instability mass gap (PIBHs). We propose that Popula…
