An international research team led by Prof. LI Di and Dr. WANG Pei from National Astronomical Observatories of Chinese Academy of Sciences (NAOC) caught an extreme episode of cosmic explosions from Fast Radio Burst (FRB) 121102, using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). A total of 1,652 independent bursts were detected within 47 days starting August 29, 2019 (UT).
It is the largest set of FRB events so far, more than the number reported in all other publications combined. Such a burst set allows for the determination, for the first time, of the characteristic energy …
