An exceptionally long gamma-ray burst was emitted by a kilonova
Three articles published in the journal “Nature” and one article published in the journal “Nature Astronomy” report various aspects of the studies conducted on the out-of-normal gamma-ray burst cataloged as GRB 211211A. Various teams of researchers used observations conducted with a series of ground-based and space telescopes to examine an event that lasted more than two hours after the actual burst. At that time, the gravitational wave detectors were not active but the event’s characteristics indicate that the origin is in a kilonova, a merger between two neutron stars.
