The Atacama Large Millimeter/submillimeter Array (ALMA) is an astronomical interferometer of 66 radio telescopes in the Atacama Desert of northern Chile, which observe electromagnetic radiation at millimeter and submillimeter wavelengths.
Very-long-baseline interferometry (VLBI) is a type of astronomical interferometry used in radio astronomy. In VLBI a signal from an astronomical radio source, such as a quasar, is collected at multiple radio telescopes on Earth or in space. The distance between the radio telescopes is then calculated using the time difference between the ...
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 Event Horizon Telescope (EHT) is a telescope array consisting of a global network of radio telescopes.The EHT project combines data from several very-long-baseline interferometry (VLBI) stations around Earth, which form a combined array with an angular resolution sufficient to observe objects the size of a supermassive black hole's event horizon.
Green Bank Observatory is a location in Fallout 76, as National Isolated Radio Array [16]; The observatory is called Camp Echo One in “Captain America: Brave New World,” with Captain America entering a radio quiet zone in West Virginia where two telescopes resemble the 100-meter Green Bank Telescope.
The concept of aperture synthesis was first formulated in 1946 by Australian radio astronomers Ruby Payne-Scott and Joseph Pawsey. Working from Dover Heights in Sydney, Payne-Scott carried out the earliest interferometer observations in radio astronomy on 26 January 1946 using an Australian Army radar as a radio telescope. [6]
The VLA is a multi-purpose instrument designed to allow investigations of many astronomical objects, including radio galaxies, quasars, pulsars, supernova remnants, gamma-ray bursts, radio-emitting stars, the sun and planets, astrophysical masers, black holes, and the hydrogen gas that constitutes a large portion of the Milky Way galaxy as well ...
Three radio telescope receivers. A minimum of three antennas are required for closure phase measurements. In the simplest case, with three antennas in a line separated by the distances a 1 and a 2 shown in diagram at the right. The radio signals received are recorded onto magnetic tapes and sent to a laboratory such as the Very Long Baseline Array.
