Plateau de Bure Interferometer

Plateau de Bure Interferometer
St Etienne en Dévoluy, France (FR)
The Plateau de Bure Interferometer is a six-antenna interferometer on the Plateau de Bure (2550 m) in the French Alps, operated by the Institut de radioastronomie millimétrique. It is specifically designed for millimetre-wave observations and specialises in studies of line emission from molecular gas and radio continuum of cold dust.

At an observing wavelength of 3 mm (100 GHz frequency) each of these telescopes can resolve two objects 45 arcseconds apart from each other on the sky. In an interferometer, these 45″ are actually the size of the field of view. So an interferometer like this one images, at very high resolution (better than 1″), structures smaller than 45″.

On July 1, 1999 20 people were killed at the crash of the aerial tramway leading up to the observatory.
