Abstract:

 In the talk, we will present the results of high precision pulsar timing of 57 millisecond pulsars conducted using the the Chinese FAST 500-meter radio telescope. Particularly, we will highlight the gravitational wave searching efforts of the Chinese Pulsar Timing Array collaboration. More backgrounds and topics on pulsar timing, nanoHertz GW detection, and gravity test will be also covered. Future Chinese perspective in the related field will be also discussed.

报告摘要：

本次报告将介绍利用中国500米口径球面射电望远镜（FAST）对57颗毫秒脉冲星进行高精度计时观测的研究成果，重点讲述中国脉冲星测时阵列（CPTA）合作组在引力波搜寻方面的研究进展，并涉及脉冲星测时、纳赫兹引力波探测与引力检验等相关背景与议题。此外，报告还将探讨中国在该领域的未来展望。
