Gamma-Ray Burst Optical/Near-Infrared Detector
The Gamma-Ray Burst Optical/Near-Infrared Detector (GROND) is an imaging instrument used to investigate
transit photometry.[1][2][3] It is operated at the 2.2-metre MPG/ESO telescope at ESO's La Silla Observatory
in the southern part of the Atacama desert, about 600 kilometres north of Santiago de Chile and at an altitude of 2,400 metres.
Discoveries
- On 13 September 2008, 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]
