Gravitational waves provide a unique tool for observational astronomy. While the first LIGO--Virgo catalogue of gravitational-wave transients (GWTC-1) contains eleven signals from black hole and neutron star binaries, the number of observations is increasing rapidly as detector sensitivity improves. To extract information from the observed signals, it is imperative to have fast, flexible, and scalable inference techniques. In a previous paper, we introduced BILBY: a modular and user-friendly Bayesian inference library adapted to address the needs of gravitational-wave inference. In this work, we demonstrate that BILBY produces reliable results for simulated gravitational-wave signals from compact binary mergers, and verify that it accurately reproduces results reported for the eleven GWTC-1 signals. Additionally, we provide configuration and output files for all analyses to allow for easy reproduction, modification, and future use. This work establishes that BILBY is primed and ready to analyse the rapidly growing population of compact binary coalescence gravitational-wave signals.

使用 Bilby 进行紧凑二元合并的贝叶斯推理：第一个 LIGO-Virgo 引力波瞬态目录的验证和应用

引力波为观测天文学提供了一种独特的工具。虽然第一个 LIGO--处女座引力波瞬变目录 (GWTC-1) 包含来自黑洞和中子星双星的 11 个信号，但随着探测器灵敏度的提高，观测数量正在迅速增加。为了从观察到的信号中提取信息，必须拥有快速、灵活和可扩展的推理技术。在之前的一篇论文中，我们介绍了 BILBY：一个模块化且用户友好的贝叶斯推理库，适用于满足引力波推理的需求。在这项工作中，我们证明 BILBY 为来自紧凑二进制合并的模拟引力波信号产生可靠的结果，并验证它准确地再现了 11 个 GWTC-1 信号报告的结果。此外，我们为所有分析提供配置和输出文件，以便于复制、修改和未来使用。这项工作表明 BILBY 已准备好并准备好分析快速增长的紧凑二元聚结引力波信号。
