论文摘要
引力波为观察天文学提供了独特的工具。尽管引力波瞬变（GWTC-1）的第一个Ligo-Virgo目录包含来自黑洞和中子星二进制的11个信号，但随着检测器敏感性的提高，观测值的数量正在迅速增加。为了从观察到的信号中提取信息，必须具有快速，灵活和可扩展的推理技术。在上一篇论文中，我们介绍了Bilby：一个模块化和用户友好的贝叶斯推断库，该库适应了引力波推理的需求。在这项工作中，我们证明了Bilby从紧凑型二进制合并中产生可靠的结果，并验证它准确地重现了11个GWTC-1信号报告的结果。此外，我们为所有分析提供了配置和输出文件，以允许易于复制，修改和将来使用。这项工作确定了Bilby已准备就绪，并准备分析紧凑型二元合并重力波信号的快速增长。
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.
