An article published in the journal “Nature Communications” describes an analysis of the gamma-ray burst cataloged as GRB150101B. A team of researchers led by Eleonora Troja of NASA pointed out the similarity between this gamma-ray burst and the electromagnetic signals emitted by the event cataloged as GW170817, the neutron star merger detected at both electromagnetic waves and gravitational waves. A year after the sensational announcement of that event, the authors of this new research believe they have discovered another one of that type.
