Web30 de jan. de 2024 · Using B-POP, we explore how BH formation channels, star cluster evolution, hierarchical mergers, and natal BH properties affect the population of BBH mergers. We find that the primary mass distribution of BBH mergers extends beyond M 1 ≃ 200 M ⊙ , and the effective spin parameter distribution hints at different natal spins for … Web7 de mar. de 2024 · We find that the hierarchical model is preferred over an alternative model with no hierarchical mergers (Bayes factor B >1400) and that GW190521 is favored to contain two second-generation black ...

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. Webmergers encounter new black holes, resulting in so-called hierarchical mergers. Hierarchical events carry signatures such as higher-than-usual black hole mass and spin. Here we show that the recently reported gravitational-wave candidate, GW170817A, could be the result of such a hierarchical merger. In particular, its chirp mass ∼40Me and
