帕克斯脉冲星计时阵

The Parkes Pulsar Timing Array

2023年,国际上几个脉冲星计时阵团队同时独立宣布发现了纳赫兹引力波背景信号的证据。这预示着一扇全新的引力波天文学观测窗口即将打开。帕克斯脉冲星计时阵是第一个正式运行的脉冲星计时阵实验,在研发先进的脉冲星观测仪器和高效的数据处理软件、发展脉冲星计时噪声分析和引力波搜寻方法等方面做出了开创引领性贡献。文章将介绍帕克斯脉冲星计时阵的发展历程、对领域的独特贡献和最新的研究成果。

In 2023,several international pulsar timing array teams independently announced evidence for a nanohertz gravitational wave background.This implies that a new gravitational wave observational window will become available soon.The Parkes Pulsar Timing Array was the first pulsar timing array experiment to have made pioneering contributions in developing advanced instrumentation for pulsar observations,efficient data reduction software,methods for pulsar timing noise analysis,and gravitational wave searches.This article presents an overview of the Parkes Pulsar Timing Array project,its unique contribution to the field,and latest research results.
