作为地面激光干涉仪的补充，脉冲定时阵列实验正在进行中，以寻找纳赫兹引力波。使用世界上最强大的射电望远镜，三个主要的国际合作已经收集了数十毫秒脉冲的∼10年高精度计时数据。本文综述了脉冲星计时实验、纳赫兹引力波探测以及各种计时阵列项目所取得的最新成果。
Complementary to ground-based laser interferometers, pul ar timing array experiments are being carried out to search fo nanohertz gravitational waves. Using the world’s most powerful radio telescopes, three major international collaborations hav e collected∼10year high precision timing data for tens of millisecond puls ars. In this paper we give an overview on pulsar timing experi m nts, gravitational wave detection in the nanohertz regime, and r ecent results obtained by various timing array projects.
