The first detection of very-high-energy gamma rays from a gamma-ray burst, deep in its afterglow.
Our part
Fabian convenes the H.E.S.S. transients working group, which runs the GRB observation programme. He was not part of the analysis of this burst.
Follow-up, step by step

The burst is detected and localised.
- T0 + 10 hH.E.S.S.
The position becomes visible from Namibia; the team decides to search for an afterglow.
- T0 + 10 to 12 hH.E.S.S.
Two hours of data reveal a new point-like source at the burst position.

Detection of very high-energy gamma-rays from GRBs
H.E.S.S. and MAGIC achieved the first detections of very-high-energy gamma rays from gamma-ray bursts, opening a new window on their afterglows.
