Latest News, International – China’s Five-hundred-meter Aperture Spherical Radio Telescope (FAST) has found strong evidence of the existence of nanohertz gravitational waves, which are critical in studying contemporary astrophysical problems such as supermassive black holes, the history of galactic mergers, and the formation of large-scale structures in the universe.
This was revealed in research conducted by scientists from the National Astronomical Observatory of the Chinese Academy of Sciences (NAOC) and a number of other institutions published online in the journal Research in Astronomy and Astrophysics on Thursday (29/6).
According to Xinhua News, research says nanohertz gravitational waves can provide clues in understanding the formation of the structure of the universe and investigate the development, evolution, and merger of the most massive celestial objects in the universe, namely supermassive black holes, according to scientists.
Scientists monitored regularly rhythmic 57-millisecond pulsars for 41 months and found important evidence for signatures of quadrupole correlation that matched predictions of nanohertz gravitational waves at the statistical confidence level of 4.6 sigma (with a probability of a false alarm of two in a million).
Li Kejia, NAOC researcher who is also a professor at Peking University, revealed that the detection of nanohertz gravitational waves is fairly difficult given their very low frequency, long period of time, and wavelengths of up to several light years.

So far, the timing observations (timing) long range to millisecond pulsars with extreme rotational stability is the only known effective way to detect nanohertz gravitational waves.
Located in an area with natural deep and circular karst depressions in southwest China’s Guizhou Province, FAST officially opened operations in January 2020.
FAST is believed to be the most sensitive radio telescope in the world.
