论文摘要
我们研究了引力波的随机背景，伴随着宇宙学的一阶相变触发的暗物质突然冻结，该相变赋予了深色物质。我们考虑通过（1）气泡滤波以及（2）通货膨胀和重新加热来产生测量的暗物质遗物丰度的模型，并表明在将来的干涉仪中可以检测到这些机制的重力波。
We study the stochastic background of gravitational waves which accompany the sudden freeze-out of dark matter triggered by a cosmological first order phase transition that endows dark matter with mass. We consider models that produce the measured dark matter relic abundance via (1) bubble filtering, and (2) inflation and reheating, and show that gravitational waves from these mechanisms are detectable at future interferometers.
