The event is designated EP240408a, as it was first detected by the Einstein Probe, an X-ray space telescope, on 8 April 2024.

The burst was linked to GRB 240315C, a gamma-ray burst, but its characteristics—like a 6-minute delay between X-rays and gamma rays—challenge existing theories of GRB formation. Weimin Yuan, ...
