论文摘要
最近的纳米级证据证明了共同源随机背景，这暗示了早期宇宙中引力波（GW）辐射。我们表明，该结果可以解释为围绕KEV-MEV窗口温度周围的一阶相变（FOPT）产生的GW频谱。在低于电动量表的温度下，在多种温暖的暗物质模型（例如Majoron Dark Matter）中，可以自然设想这样的FOPT。
The recent NANOGrav evidence of a common-source stochastic background provides a hint to Gravitational Waves (GW) radiation from the Early Universe. We show that this result can be interpreted as a GW spectrum produced from First Order Phase Transitions (FOPTs) around a temperature in the KeV-MeV window. Such a class of FOPTs at temperatures much below the electroweak scale can be naturally envisaged in several Warm Dark Matter models such as Majoron Dark Matter.
