Interféromètre radio
Combines antennas to synthesize a much larger aperture.
Aperçu
Radio interferometers combine signals from separated antennas to synthesize the resolution of a single telescope spanning their separation. Aperture-synthesis imaging opened the radio sky to detailed study of relativistic jets, cold gas and the early universe.
Découvertes clés
- Aperture-synthesis mapping of radio sources
- Imaging of relativistic jets in radio galaxies
- Principle behind the VLA, ALMA and the Event Horizon Telescope
