论文摘要
脉冲星定时阵列(PTA)观察的Nanograv合作最近宣布了各向同性随机过程的证据,这可能是对随机重力波(GW)背景的首次检测。我们讨论信号是由与太阳质量原始黑洞(PBHS)形成相关的二阶GW引起的。可以通过未来的干涉仪类型的GW观测值来测试这种可能性,该观测值针对太阳能质量PBH的合并事件以及PTA观测值的更新。
The NANOGrav collaboration for the pulsar timing array (PTA) observation recently announced evidence of an isotropic stochastic process, which may be the first detection of the stochastic gravitational-wave (GW) background. We discuss the possibility that the signal is caused by the second-order GWs associated with the formation of solar-mass primordial black holes (PBHs). This possibility can be tested by future interferometer-type GW observations targeting the stochastic GWs from merger events of solar-mass PBHs as well as by updates of PTA observations.
