JIVE’s mandate is to support the operations and users of the European VLBI Network (EVN), in the widest sense.Very Long Baseline Interferometry (VLBI) is a type of astronomical interferometry used in radio astronomy. It allows observations of an object that are made simultaneously by many telescopes to be combined, emulating a telescope with a size equal to the maximum separation between the telescopes. Normally the participating radio telescopes function individually, working on their own specific projects. In the case of VLBI, they all observe the same source at the same time, allowing much higher spatial resolution. There are many complex and challenging hurdles that need to be overcome to enable this effort. One challenge is the data processing requirement. JIVE operates the EVN data processor, known as the correlator – a special-purpose supercomputer for astronomical VLBI data correlation.       (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4Organisation of JIVE[edit]JIVE is located in Dwingeloo, the Netherlands and is hosted by the Netherlands Institute for Radio Astronomy (ASTRON).JIVE has seven members:JIVE is also supported by the following participating research institutes:National Astronomical Observatories of China (NAOC), ChinaMax Planck Institute for Radio Astronomy (MPIfR), GermanyNational Institute for Astrophysics (INAF), ItalyNational Research Federation (NRF), South AfricaThere are currently 22 telescopes in the EVN.       (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4Observations using the EVN can also be carried out in real-time, thus earning the name of e-VLBI (electronic Very Long Baseline Interferometry). The telescopes are then linked via high-speed national research and education networks (NRENs) which overcome some of the performance drawbacks of TCP\/IP and UDP\/IP (networking protocols) to allow sharing large volumes of data for immediate use. Such high-speed networks eliminate the shipping of disks of data from separate observations for correlation, thus allowing astronomers to respond to events as they happen in real time. The VLBI data are streamed to JIVE, where they are correlated and the final, high-resolution image created.In a demonstration of e-VLBI as part of 100 Hours of Astronomy[1] in 2009 14 telescopes from Australia, Chile, China, Finland, Germany, Italy, the Netherlands, Poland, Puerto Rico, Spain, Sweden and the UK participated in joint observations of the active galaxy 3C120. The participating telescopes included:[2]the 26 meter telescope at Hobart, operated by the University of Tasmania;the 22m dish of Mopra, part of the Long Baseline Array, operated by CSIRO;the 25m dish of Sheshan near Shanghai, operated by the Shanghai Astronomical Observatory, Chinese Academy of Sciences;the 14m Mets\u00e4hovi dish, operated by the Aalto University;the 32m telescope of Toru\u0144;the 32m telescope at Medicina, operated by the Instituto Nazionale di Astrofisica;the 25m telescope at the Onsala Space Observatory;the Westerbork Synthesis Radio Telescope;the Yebes 40m, operated by the Observatorio Astronomico Nacional;the 300m dish of Arecibo, located in Puerto Rico;the 6m dish of TIGO, operated by the Geod\u00e4tisches Observatorium Wettzell.References[edit]External links[edit]ConceptsRadio telescopes(List)IndividualtelescopesInterferometersAllen Telescope Array (ATA, California, US)Atacama Large Millimeter Array (ALMA, Chile)Australia Telescope Compact Array (ATCA, Australia)Australian Square Kilometre Array Pathfinder (ASKAP, Australia)Canadian Hydrogen Intensity Mapping Experiment (CHIME, Canada)Combined Array for Research in Millimeter-wave Astronomy (CARMA, California, US)European VLBI Network (Europe)Event Horizon Telescope (EHT)Giant Metrewave Radio Telescope (GMRT, India)Green Bank Interferometer (GBI, West Virginia, US)Korean VLBI Network (KVN, South Korea)Large Latin American Millimeter Array (LLAMA, Argentina\/Brazil)Long Wavelength Array (LWA, New Mexico, US)Low-Frequency Array (LOFAR, Netherlands)MeerKAT (South Africa)Molonglo Observatory Synthesis Telescope (MOST, Australia)Multi-Element Radio Linked Interferometer Network (MERLIN, UK)Murchison Widefield Array (MWA, Australia)Northern Cross Radio Telescope (Italy)Northern Extended Millimeter Array (France)One-Mile Telescope (UK)Primeval Structure Telescope (PaST, China)Square Kilometre Array (SKA, Australia, South Africa)Submillimeter Array (SMA, US)Very Large Array (VLA, New Mexico, US)Very Long Baseline Array (VLBA, US)Westerbork Synthesis Radio Telescope (WSRT, Netherlands)Space-basedObservatoriesMulti-usePeopleAstronomy byEM methodsRelated articles       (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4"},{"@context":"http:\/\/schema.org\/","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"https:\/\/wiki.edu.vn\/en\/wiki21\/#breadcrumbitem","name":"Enzyklop\u00e4die"}},{"@type":"ListItem","position":2,"item":{"@id":"https:\/\/wiki.edu.vn\/en\/wiki21\/joint-institute-for-vlbi-eric\/#breadcrumbitem","name":"Joint Institute for VLBI ERIC"}}]}]
