China’s five-hundred-meter aperture spherical radio telescope (FAST), the world’s largest single-dish radio telescope, has identified more than 240 pulsars, according to the National Astronomical Observers of the Chinese Academy of Sciences.

Based on the data collected by FAST, the scientists published over 40 quality papers. With the help of the advanced telescope, Chinese research teams have become a key force in the study of fast radio bursts.

Researchers from the National Astronomical Observatories used FAST to observe a repetitive fast radio burst called FRB180301 and found various oscillations in the polarization angle, which provide an overview of the origin of the fast radio bursts. The research was published in the journal Nature in October.

Researchers from Peking Normal University, Peking University and National Astronomical Observatories used FAST to detect an extremely intense radio blast from the galactic magnetar SGR 1935 2154 and found that the phenomenon was related to very special physical conditions. The research was published Thursday in the journal Nature.

FAST has immense potential for detecting fast radio bursts and gravitational waves, providing data support for research on the physical process of the Big Bang.
