宇宙微波背景辐射（CMB）的B模偏振提供了暴胀引力波（IGWs）的重要信息，基于这一研究进展，我们研究了利用未来天基引力波（GW）探测器获取早期宇宙信息的可能性。我们进行了详细的统计分析，以估计我们可以确定膨胀后的再加热温度以及膨胀引力波的振幅，张量谱指数和运行。我们讨论的精度如何依赖于检测器的噪声参数和分析中可用的最小频率。本文还讨论了这种研究对通货膨胀模型检验的意义。
Motivated by recent progress in our understanding of the B-mode polarization of cosmic microwave background (CMB), which provides important information about the inflationary gravitational waves (IGWs), we study the possibility to acquire information about the early universe using future space-based gravitational wave (GW) detectors. We perform a detailed statistical analysis to estimate how well we can determine the reheating temperature after inflation as well as the amplitude, the tensor spectral index, and the running of the inflationary gravitational waves. We discuss how the accuracies depend on noise parameters of the detector and the minimum frequency available in the analysis. Implication of such a study on the test of inflation models is also discussed.
