The day-long, repeating GRB 250702BDE / EP250702a: A unique extragalactic transient

Andrew J. Levan, Antonio Martin-Carrillo, Tanmoy Laskar +42

Gamma-ray bursts (GRBs) are singular outbursts of high-energy radiation with durations typically lasting from milliseconds to minutes and, in extreme cases, a few hours. They are a…
