Short Gamma-Ray Burst Localized to Extremely Distant Galaxy..
Sci-News.com reports: “The gamma-ray light lasts for less than two seconds, while the optical light can last for a matter of hours before fading. Therefore, rapid follow-up of the optical afterglow of these intense flashes of gamma-ray radiation is critical.”
“Astronomers typically only detect 7-8 SGRBs each year that are well-localized enough for further observations. GRB 181123B was detected on November 23, 2018, by NASA’s Neil Gehrels Swift Observatory.”
