Construction of the Mullard Radio Astronomy Observatory commenced at Lords Bridge Air Ammunition Park, [1] a few kilometres to the west of Cambridge. The observatory was founded under Martin Ryle of the Radio-Astronomy Group of the Cavendish Laboratory , University of Cambridge and was opened by Sir Edward Victor Appleton on 25 July 1957.
38-element radio telescope interferometer working in the frequency range of 1.2–6.0 GHz. The final baseline will be 2.27 km in the East-West and 1.17 km in the South directions, respectively. This instrument will obtain radio images from the sun with a spatial resolution ≈4x6 arc seconds.
Zygo Corporation, or simply Zygo, is a manufacturer headquartered at Middlefield, Connecticut, that specializes in optical systems and equipment.Their metrology product lines include 3D measuring microscopes using coherence scanning interferometry, laser Fizeau interferometers for testing optical components, laser displacement interferometers, and heterodyne optical encoders for stage position ...
1946 – Martin Ryle and his group perform the first astronomical observations with a radio interferometer; 1947 – Bernard Lovell and his group complete the Jodrell Bank 218-foot (66 m) non-steerable radio telescope; 1949 – Palomar 48-inch (1.2 m) Schmidt optical reflecting telescope begins operation, located in Palomar, California
The Arcminute Microkelvin Imager (AMI) consists of a pair of interferometric radio telescopes - the Small and Large Arrays - located at the Mullard Radio Astronomy Observatory near Cambridge. AMI was designed, built and is operated by the Cavendish Astrophysics Group .
The European VLBI Network (EVN) is a network of radio telescopes located primarily in Europe and Asia, with additional antennas in South Africa and Puerto Rico, which performs very high angular resolution observations of cosmic radio sources using very-long-baseline interferometry (VLBI). The EVN is the most sensitive VLBI array in the world ...
A radio telescope is a specialized antenna and radio receiver used to detect radio waves from astronomical radio sources in the sky. [ 1 ] [ 2 ] [ 3 ] Radio telescopes are the main observing instrument used in radio astronomy , which studies the radio frequency portion of the electromagnetic spectrum , just as optical telescopes are used to ...
In 1946 Ryle built the first multi-element astronomical radio interferometer. [10] Ryle guided the Cambridge radio astronomy group in the production of several important radio source catalogues. One such catalogue, the Third Cambridge Catalogue of Radio Sources (3C) in 1959 helped lead to the discovery of the first quasi-stellar object .
