For the first time, researchers have succeeded in detecting the structuring of the universe through quasars, according to the National Astronomical Observations (NAOC) of the Chinese Academy of Sciences Monday.
The work was carried out by the international group of eBOSS, the biggest ongoing spectroscopic survey in the world, which detected redshift distortions signals while observing the spatial distribution of quasars that are 6.8 to 10.5 billion light years from earth.
Redshift distortion is a special three-dimensional cluster mode developed by stars under the effect of gravitational potential, and is also considered to be one of the most significant probes in researching gravitation on the cosmological level because of its direct correlation with gravitation.
The signals discovered now were produced during the time when the universe was just one third or half the size of today, based on a report featured by the eBOSS group on the finding.
The discovery is vital for future research in innovative cosmological subjects such as the essence of gravitation and dark energy.
eBOSS, launched in 2014, has attracted research institutes from several countries, including the NAOC. (Xinhua)
