WebWe run 12 different simulations, varying the mass of galaxies, type of galaxies, and initial population of black holes. We find that not all nuclear star cluster are excellent for hierarchical mergers. Small escape velocity in lighter nuclear star clusters and long dynamical timescales in heavier nuclear star clusters stops hierarchical mergers. Web26 de out. de 2024 · Further, we show that ∼2% of BBH mergers in nuclear star clusters (NSCs) may instead be of hierarchical mergers, while the percentage in globular clusters (GCs) is only a few tenths of a percent. However, the rates of hierarchical merger in GCs and NSCs are about the same, namely of ∼풪(10 −2 ) Gpc −3 yr −1 , because the total …
Web21 de jun. de 2024 · Hierarchical mergers at traps in AGNs will exhibit black hole spins (anti)aligned with the binary's orbital axis, a distinct property from other hierarchical channels. Our results suggest, although not definitively (with odds ratio of ∼1), that LIGO's heaviest merger so far, GW170729, could have originated from this channel. Web26 de jul. de 2024 · Hierarchical mergers have unique GW signatures that make them distinguishable from BHs resulting from stellar collapse. Higher-generation BHs present, on average, both higher masses and higher spins.
