Searching for Gravitational Wave Background with Chinese Pulsar Timing Array Data Release I

Explore the groundbreaking research on gravitational wave detection using pulsar timing arrays in this 38-minute conference talk from the ICBS2024. Delve into the Chinese Pulsar Timing Array (CPTA) project and its first data release, which utilizes observations from Chinese radio telescopes, including the Five-hundred-meter Aperture Spherical radio Telescope. Learn about the statistical analysis of data from 57 millisecond pulsars, revealing evidence of a correlated signal potentially indicating a gravitational wave background. Discover the key findings, including the detection of Hellings-Downs correlation with 4.6σ statistical significance at 14 nHz frequency. Gain insights into the future prospects of nHz gravitational wave background detection through international collaborations and upcoming CPTA data releases.
