论文摘要
我们指出，随机通货膨胀引力波背景有一个高频尾巴，其比例为$ f^{ - 1/2} $，带有频率$ f $。这项贡献来自重新加热阶段的加拉孔相干振荡所扩增的重力真空波动。它包含有关充气性特性（例如充气质量）以及早期宇宙的热历史的信息。
We point out that there is a high-frequency tail of the stochastic inflationary gravitational wave background that scales as $f^{-1/2}$ with frequency $f$. This contribution comes from the graviton vacuum fluctuation amplified by the inflaton coherent oscillation during the reheating stage. It contains information on inflaton properties such as the inflaton mass as well as the thermal history of the early Universe.
