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. fishery road bray https://erikcroswell.com

WebThese earlier “hierarchical” mergers leave distinguishable traces, like specific spin magnitudes, in their descendent black holes. Such traces can be seen through gravitational wave analysis. In this talk, Maya Fishbach will share results that indicate hierarchical mergers are uncommon, especially among black holes smaller than roughly 60 solar … WebSo, hierarchical mergers up to 3g−3g can occur from the most overmassive GCs if and only if the natal spins of BH are extremely small (e.g. Fuller & Ma 2024). However, the highest generation mergers due to GCs always occur after the bound BBH is ejected from the cluster (Rodriguez et al. 2024).
