Intermediate mass black holes from stellar mergers in young star clusters
Ugo N. Di Carlo, Michela Mapelli, Mario Pasquato +8
Intermediate mass black holes (IMBHs) in the mass range bridge the gap between stellar black holes (BHs) and supermassive BHs. Here, we investigate…

GW190521 formation via three-body encounters in young massive star clusters
Marco Dall'Amico, Michela Mapelli, Ugo N. Di Carlo +5
GW190521 is the most massive binary black hole (BBH) merger observed to date, and its primary component lies in the pair-instability (PI) mass gap. Here, we investigate the formati…

Hierarchical black hole mergers in young, globular and nuclear star clusters: the effect of metallicity, spin and cluster properties
Michela Mapelli, Marco Dall'Amico, Yann Bouffanais +8
We explore hierarchical black hole (BH) mergers in nuclear star clusters (NSCs), globular clusters (GCs) and young star clusters (YSCs), accounting for both original and dynamicall…
