  • In the last 3000 yr, one significant and rapid increase in the concentration of 14 Ci n tree rings was observed; it corresponds to a γ -ray energy input of 7 × 10 24 erg at Earth within up to one year in AD 774/5. A normal supernova and a solar or stellar flare are unlikely as cause, so that the source remained unknown. Here, we show that a short gamma-ray burst (GRB) in our Galaxy is consistent with all observables: such an event is sufficiently short and provides the necessary energy in the… CONTINUE READING
