An article published in the journal “Monthly Notices of the Royal Astronomical Society” reports a study on the short-duration gamma-ray burst cataloged as GRB160821B that has characteristics that match those of the merger of neutron stars observed at both electromagnetic waves and gravitational waves on August 17, 2017. A team of researchers led by Eleonora Troja of the University of Maryland used data collected from various telescopes to compare the two events and the 2016 one was observed since its early hours providing new information on the initial phase of what’s called a kilonova.
