Measuring the Hubble constant using gravitational-wave signals from compact binaries, in combination with redshift information from galaxy catalogues, could be key to resolving the current Hubble constant tension. However, this method has only been applied to a few dozen gravitational-wave events so far. This project will use advanced computational methods to scale this analysis to thousands of events and extend it to include more cosmological parameters, in preparation for future observing runs and third-generation detectors.

利用来自致密双星的引力波信号测量哈勃常数，结合来自星系目录的红移信息，可能是解决当前哈勃常数张力的关键。然而，到目前为止，这种方法只应用于几十个引力波事件。该项目将使用先进的计算方法将这种分析扩展到数千个事件，并将其扩展到包括更多的宇宙学参数，为未来的观测运行和第三代探测器做准备。
