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 ...
The Chinese Deep Space Network (CDSN) is a network of large antennas and communication facilities that are used for radio astronomy, radar observations, and spacecraft missions of China. The CDSN is managed by the China Satellite Launch and Tracking Control Center General (CLTC) of the People's Liberation Army Strategic Support Force Space ...
It was formed in 1962 from the merger of the Xujiahui (also romanized as "Ziikawei") and Sheshan (Zose) observatories in Shanghai. It was involved with the Chang'e 1 Moon mission as the VLBI array is used for position determinations. In October 2012 the Tian Ma 65-meter (213 ft) radio telescope was completed for SHAO. [1]
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 ...
European VLBI Network (EVN) Distributed across Europe with members in China, South Africa and the US VLBI array operated by the European Consortium for VLBI: Plateau de Bure Interferometer: Plateau de Bure, Grenoble, France Originally an array of 3 antennas, since 2005 has 6 antennas, operating at millimeter wavelengths, now part of NOEMA
The main goals of the QTT include imaging of pulsars, stellar formation, and the large-scale radio structure of the universe. [7] [4] Other goals are the use of Pulsar Timing Arrays to detect nanoHertz gravitational waves, to be part of Very Long Baseline Interferometry, to study the interstellar medium, to study galaxies and black holes, to study dark matter and to carry out astrometry.
The DSOC also serves as the control center for the Very Long Baseline Array (VLBA), a VLBI array of ten 25-meter dishes located from Hawaii in the west to the U.S. Virgin Islands in the east that constitutes the world's largest dedicated, full-time astronomical instrument.
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.
