Briefings

Astronomers identified the longest central engine activity from a gamma-ray burst, lasting approximately 27 days in the burst's rest frame. This duration exceeds the previous record by about 20 days. The event occurred at a redshift of 0.8577, and the analysis was conducted on a preprint posted to arXiv on September 18, 2026.

Key points

• The gamma-ray burst at redshift 0.8577 exhibited central engine activity lasting approximately 27 days in the burst's rest frame, surpassing the previous record by roughly 20 days.
• The study was published as a preprint on arXiv on September 18, 2026, exploring potential mechanisms powering this unusually long-lived phenomenon.

Context and limitations

The evidence is limited to a single preprint on arXiv; observational data and full results are not yet available.
