Abstract

In 2016, the Laser Interferometer Gravitational-Wave Observatory (LIGO) announced the detection of a 100 Hz gravitational wave produced by the merger of two stellar mass black holes, from which the era of gravitational wave astronomy began. After decades of effort, in June 2023, four pulsar time array collaborations around the world reported progress in the search for the low-frequency symphony of the universe——the nanohertz gravitational waves. This paper will describe the history and data of one of these organizations, the Chinese Pulsar Time Array project, as well as its progress in the detection of nanohertz gravitational waves and its future prospects.
