Floor S. Broekgaarden, Sharan Banagiri, Ethan Payne

AI总结:

本文通过可视化展示了双致密天体并合引力波探测数量受分析流程等因素影响而存在的不确定性,并预测了下一代探测器未来每年数百万次探测的指数级增长前景,同时提供了公开代码。

摘要:

迄今为止,我们已经观测到了多少次来自双致密天体并合的引力波事件?这个看似简单的问题,出人意料地给出了一个有些模糊的答案,该答案取决于所选的数据分析流程、探测阈值以及其他潜在假设。为了说明这一点,我们基于文献中的最新结果,提供了对截至第三次观测运行(O3)结束时双致密天体并合现有探测数量的可视化。此外,我们还对未来一代探测器预期的观测数量进行了可视化,强调了当像 Cosmic Explorer 和 Einstein Telescope 这样的下一代地面探测器上线运行时,每年探测数量可能高达数百万次的可能性。我们提供了一个公开可用的代码,突显了未来几十年引力波观测的指数级增长,以及引力波(天体)物理学令人振奋的前景。

英文摘要:

How many gravitational-wave observations from double compact object mergers have we seen to date? This seemingly simple question surprisingly yields a somewhat ambiguous answer that depends on the chosen data-analysis pipeline, detection threshold and other underlying assumptions. To illustrate this we provide visualizations of the number of existing detections from double compact object mergers by the end of the third observing run (O3) based on recent results from the literature. Additionally, we visualize the expected number of observations from future-generation detectors, highlighting the possibility of up to millions of detections per year by the time next-generation ground-based detectors like Cosmic Explorer and Einstein Telescope come online. We present a publicly available code that highlights the exponential growth in gravitational-wave observations in the coming decades and the exciting prospects of gravitational-wave (astro)physics.
