The Gamma-Ray Burst Optical/Near-Infrared Detector (GROND) is an imaging instrument used to investigate Gamma-Ray Burst afterglows and do follow-up observations on transiting exoplanets. It is operated at the MPG 2.2m telescope at the La Silla Observatory.[1][2][3]
Discoveries
- On 13 September 2008, Swift detected gamma-ray burst 080913. GROND and VLT subsequently placed the GRB at 12.8 Gly distant, making it the most-distant GRB observed, as well as the second-most-distant object to be spectroscopically confirmed.[4][5]
- On 15 September 2008, NASA's Fermi Gamma-ray Space Telescope detected gamma-ray burst 080916C. On 19 February 2009, NASA announced that the GROND team's work shows that the GRB was the most energetic yet observed, and 12.2 Gly distant.[6][7]
