我们调查的潜力，观察引力波从宇宙学相变丽莎在最近的理论和实验的发展。我们的分析是基于目前最先进的模拟宇宙流体中的声波后，相变完成。我们讨论了引力辐射的各种来源，描述相变的基本参数和各种可行的粒子物理模型，澄清文献中出现的常见误解，并确定需要进一步研究的开放问题。我们还提出了一个基于网络的工具，PTPlot，它允许用户获得最新的检测前景为一组给定的相变参数在丽莎。
We investigate the potential for observing gravitational waves from cosmological phase transitions with LISA in light of recent theoretical and experimental developments. Our analysis is based on current state-of-the-art simulations of sound waves in the cosmic fluid after the phase transition completes. We discuss the various sources of gravitational radiation, the underlying parameters describing the phase transition and a variety of viable particle physics models in this context, clarifying common misconceptions that appear in the literature and identifying open questions requiring future study. We also present a web-based tool, PTPlot, that allows users to obtain up-to-date detection prospects for a given set of phase transition parameters at LISA.
