Since the first signal in 2015, the gravitational-wave detections of merging binary black holes (BBHs) by the LIGO and Virgo collaborations (LVC) have completely transformed our understanding of the lives and deaths of compact object binaries, and have motivated an enormous amount of theoretical work on the astrophysical origin of these objects. We show that the phenomenological fit to the redshift-dependent merger rate of BBHs from Abbott et al. is consistent with a purely dynamical origin for these objects, and that the current merger rate of BBHs from the LVC could be explained entirely with globular clusters alone. While this does not prove that globular clusters are the dominant formation channel, we emphasize that many formation scenarios could contribute a significant fraction of the current LVC rate, and that any analysis that assumes a single (or dominant) mechanism for producing BBH mergers is implicitly using a specious astrophysical prior.

自 2015 年第一个信号以来，LIGO 和 Virgo 合作 (LVC) 对合并双黑洞 (BBH) 的引力波探测彻底改变了我们对致密双星生死的理解，并激发了巨大的动力关于这些天体的天体物理学起源的理论工作。我们证明了 Abbott 等人的 BBH 的红移依赖合并率的现象学拟合。与这些天体的纯动态起源一致，并且当前来自 LVC 的 BBH 的合并率可以完全用球状星团来解释。虽然这并不能证明球状星团是主要的形成通道，但我们强调许多形成情景可能占当前 LVC 率的很大一部分，
