Pair-instability Gap Black Holes in Population III Star Clusters: Pathways, Dynamics, and Gravitational-wave Implications

Pair-instability Gap Black Holes in Population III Star Clusters: Pathways, Dynamics, and Gravitational-wave Implications

The detection of the gravitational-wave (GW) event GW190521 raises questions about the formation of black holes (BHs) within the pair-instability mass gap (PIBHs). We propose that Population III star clusters significantly contribute to events similar to GW190521. We perform N -body simulations and...
