我们研究了LIGO/Virgo/KAGRA探测器的探测范围，以寻找早期宇宙中一阶相变的特征。利用前三次观测运行的数据，我们得出了潜在引力波背景参数的约束条件，重点关注以强过冷为特征的跃迁。作为我们分析的一个应用，我们确定了两个具有代表性的粒子物理模型的参数空间边界。我们还评论了第三代探测器探测过冷相变的预期范围。
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.
