合并双星黑洞产生的引力波可以用来阐明大质量双星恒星演化中人们知之甚少的方面，例如大质量恒星的演化（包括它们的质量损失率），共同的包络相，以及大质量恒星在整个宇宙历史中形成的速率。在本文中，我们探讨的\emph{correlated}的影响，这些阶段的合并率和啁啾质量分布的合并双黑洞的预测，旨在确定可能的模型参数之间的退化。在我们的许多模型中，很大一部分（超过70%的可检测的双黑洞）来自化学均匀演化的情况下，这些模型往往过度预测双黑洞合并率和生产系统的平均质量太大。我们的首选模型有利于增强质量损失率的氦丰富的沃尔夫-拉叶星，在紧张局势与最近的理论和观测的发展。我们确定沃尔夫-拉叶星的质量损失率和宇宙的金属丰度演化的速度和合并的二元黑洞的属性的影响之间的相关性。基于观测到的质量分布，我们认为啁啾质量大于$40$ M $_\odot$（我们的模型预测的最大值）的双星黑洞的$\sim 10\%$不太可能通过孤立的双星演化形成，这意味着来自其他形成通道（如致密星团或活动星系核）的显著贡献（> 10%）。我们的模型将使推理的不确定参数在不久的将来二进制进化。
英文摘要：
Gravitational waves from merging binary black holes can be used to shed light on poorly understood aspects of massive binary stellar evolution, such as the evolution of massive stars (including their mass-loss rates), the common envelope phase, and the rate at which massive stars form throughout the cosmic history of the Universe. In this paper we explore the \emph{correlated} impact of these phases on predictions for the merger rate and chirp mass distribution of merging binary black holes, aiming to identify possible degeneracies between model parameters. In many of our models, a large fraction (more than 70% of detectable binary black holes) arise from the chemically homogeneous evolution scenario; these models tend to over-predict the binary black hole merger rate and produce systems which are on average too massive. Our preferred models favour enhanced mass-loss rates for helium rich Wolf--Rayet stars, in tension with recent theoretical and observational developments. We identify correlations between the impact of the mass-loss rates of Wolf--Rayet stars and the metallicity evolution of the Universe on the rates and properties of merging binary black holes. Based on the observed mass distribution, we argue that the $\sim 10\%$ of binary black holes with chirp masses greater than $40$ M$_\odot$ (the maximum predicted by our models) are unlikely to have formed through isolated binary evolution, implying a significant contribution (> 10%) from other formation channels such as dense star clusters or active galactic nuclei. Our models will enable inference on the uncertain parameters governing binary evolution in the near future.

Polluting the pair-instability mass gap for binary black holes through super-Eddington accretion in isolated binaries
单恒星演化理论预测黑洞（BH）的质量分布在大约45- 130 M $_{\odot}$之间，即所谓的“对不稳定质量间隙”。我们研究是否BH可以污染的差距后，从恒星的同伴吸积。为此，我们模拟的演化孤立的二进制使用人口合成代码，我们允许超级爱丁顿吸积。在我们最极端的假设下，我们发现最多约2%的所有合并的二进制BH系统包含一个BH的质量在对不稳定的质量差距，我们发现，不到0.5%的合并系统的总质量大于90 M $_{\odot}$。没有发现总质量超过100 M $_{\odot}$的并合BH系统。我们比较我们的结果预测从几个动力学途径对不稳定的质量间隙事件，并讨论了可区分的功能。我们的结论是，经典的孤立二元形成情景不会显着导致对不稳定质量间隙的污染。的鲁棒性的预测质量差距的孤立的二进制通道是有前途的前景放置约束（一）不同的形成渠道的相对贡献，（二）的物理学的祖细胞，包括核反应率，和（iii），暂时，哈勃参数。
