Hierarchical mergers
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. 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 …

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. Web8 de mar. de 2024 · There is much debate about the channels for astrophysical origins of the stellar-mass binary black hole (BBH) mergers detected by LIGO and Virgo. Active galactic nuclei (AGNs) are promising sites for the efficient formation and rapid mergers of BBHs due to migration traps in high-density gas disks within an inner radii. In this paper, we carry …

We use simple models …
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 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 …
