论文摘要
目前有$ {\ cal o}(100)$从天文学文献中报道的紧凑型二进制合并的引力波候选者。随着探测器敏感性的提高,目录的大小将膨胀:在A+时代首先到$ {\ cal o}(1000)$事件,然后在第三代观测器(如Cosmic Explorer和Einstein Telescope)等第三代观测师时代的$ {\ cal O}(10^6)$事件。使用贝叶斯推断对每个事件进行分析,以确定源的特性,包括组件质量,旋转,潮汐参数以及与源的距离。这些推论产品是一些最令人兴奋的引力波科科学的饲料,使我们能够用标准警报器测量宇宙的扩展,表征状态的中子星方程,并揭示组装重力波源的方式和地点。为了最大程度地利用即将到来的探测泛滥的科学,我们介绍了GWCloud,这是一个可搜索的存储库,用于创建和策划引力波推理产品。它的设计考虑了五个支柱:结果的统一性,结果的可重复性,结果的稳定性,访问天文学群落以及有效利用计算资源。我们描述了如何将GWCLOUD与示例一起使用,读者可以使用伴随代码将其复制到本文中。我们描述了我们对GwCloud的长期愿景。
There are at present ${\cal O}(100)$ gravitational-wave candidates from compact binary mergers reported in the astronomical literature. As detector sensitivities are improved, the catalog will swell in size: first to ${\cal O}(1000)$ events in the A+ era and then to ${\cal O}(10^6)$ events in the era of third-generation observatories like Cosmic Explorer and the Einstein Telescope. Each event is analyzed using Bayesian inference to determine properties of the source including component masses, spins, tidal parameters, and the distance to the source. These inference products are the fodder for some of the most exciting gravitational-wave science, enabling us to measure the expansion of the Universe with standard sirens, to characterise the neutron star equation of state, and to unveil how and where gravitational-wave sources are assembled. In order to maximize the science from the coming deluge of detections, we introduce GWCloud, a searchable repository for the creation and curation of gravitational-wave inference products. It is designed with five pillars in mind: uniformity of results, reproducibility of results, stability of results, access to the astronomical community, and efficient use of computing resources. We describe how to use GWCloud with examples, which readers can replicate using the companion code to this paper. We describe our long-term vision for GWCloud.
