DESCRIPTION:Speakers: Tong Hui (Monash University/CITA)\nUncovering the or
 igins of binary black holes through gravitational-wave detections provides
  a powerful probe of the evolution\, interactions\, and environments of ma
 ssive stars. Stellar theory predicts a forbidden range of black-hole masse
 s between 50-130Msun due to pair-instability supernovae. In this talk\, I 
 will present our latest observational evidence of the pair-instability gap
  in the distribution of black hole masses. While the gap is not present in
  the distribution of primary masses\, it appears unambiguously in the dist
 ribution of secondary masses. The location of the gap lines up well with a
  previously identified transition in the binary black-hole spin distributi
 on\; binaries with primary components in the gap tend to spin more rapidly
  than those below the gap. We interpret these findings as evidence for a s
 ubpopulation of hierarchical mergers. I will also highlight the concurrent
  signatures of hierarchical mergers. If time permits\, I will introduce th
 e results of the astrophysical distributions of merging compact objects in
  the latest GWTC-5 LVK paper.\n\nhttps://indico.itp.ac.cn/event/417/contri
