论文摘要
我们在寻找早期宇宙中一阶相变的签名时研究了Ligo/Wigo/Kagra探测器的范围。利用前三个观测运行中的数据，我们对基础引力波背景的参数产生了约束，重点是以强高冷的特征。作为分析的应用，我们确定了两个代表性粒子物理模型的参数空间的界限。我们还评论了探测超冷相变的第三代探测器的预期覆盖率。
We investigate the reach of the LIGO/Virgo/KAGRA detectors in the search for signatures of first-order phase transitions in the early Universe. Utilising data from the first three observing runs, we derive constraints on the parameters of the underlying gravitational-wave background, focusing on transitions characterised by strong supercooling. As an application of our analysis, we determine bounds on the parameter space of two representative particle physics models. We also comment on the expected reach of third-generation detectors in probing supercooled phase transitions.
