Probing the Universe’s Secrets: Key Evidence for NanoHertz Gravitational Waves

The Chinese Pulsar Timing Array (CPTA) collaboration has identified evidence of nanohertz gravitational waves using the Five-hundred-meter Aperture Spherical Radio Telescope (FAST). Despite their shorter data set, their high sensitivity yielded results comparable to other international groups. This discovery is pivotal in understanding the Universe’s structure and behavior of supermassive black holes, paving the way for future exploration of gravitational waves.
