Ground wide angle camera array detects prompt optical emission of gamma-ray burst

Researchers led by Dr. Xin Liping from the Space-based Multi-band Astronomical Variable Objects Monitor (SVOM) research team, National Astronomical Observatories of the Chinese Academy of Sciences (NAOC), have detected the prompt optical emission and its transition to the early afterglow of a gamma-ray burst (GRB 201223A), using the Ground Wide Angle Camera Array (GWAC) located at Xinglong Observatory of NAOC. The study was published in Nature Astronomy on April 10.
