Murchison Widefield Array (original) (raw)
Das Murchison Widefield Array (MWA) ist ein Radioteleskop in Australien. Es zeichnet sich durch eine große Zahl sehr einfacher und kostengünstiger Antennen aus, die über eine große Fläche im australischen Outback verteilt sind. Im Gegensatz zu vielen anderen Radioteleskopen besitzt das MWA keine beweglichen Teile. Dennoch kann das Teleskop Radiosignale gezielt aus einer Richtung empfangen. Der Richtempfang geschieht auf elektronischem Weg.

| dbo:abstract | Das Murchison Widefield Array (MWA) ist ein Radioteleskop in Australien. Es zeichnet sich durch eine große Zahl sehr einfacher und kostengünstiger Antennen aus, die über eine große Fläche im australischen Outback verteilt sind. Im Gegensatz zu vielen anderen Radioteleskopen besitzt das MWA keine beweglichen Teile. Dennoch kann das Teleskop Radiosignale gezielt aus einer Richtung empfangen. Der Richtempfang geschieht auf elektronischem Weg. (de) The Murchison Widefield Array (MWA) is a joint project between an international consortium of organisations to construct and operate a low-frequency radio array. 'Widefield' refers to its very large field of view (on the order of 30 degrees across). Operating in the frequency range 70–300 MHz, the main scientific goals of the MWA are to detect neutral atomic Hydrogen emission from the cosmological Epoch of Reionization (EoR), to study the sun, the heliosphere, the Earth's ionosphere, and radio transient phenomena, as well as map the extragalactic radio sky. It is located at the Murchison Radio-astronomy Observatory (MRO). Along with the Australian Square Kilometre Array Pathfinder (ASKAP), also at the MRO, and two radio telescopes in South Africa, the Hydrogen Epoch of Reionization Array (HERA) and MeerKAT, the MWA is one of four precursors to the international project known as the Square Kilometre Array (SKA). (en) Le Murchison Widefield Array, aussi connu sous l'acronyme MWA, est un radiotélescope basses fréquences géant, situé à Meekatharra en Australie-Occidentale qui a été officiellement mis en service le 9 juillet 2013, dont le but est d'approfondir l'étude de l'univers depuis sa naissance. Il est le premier bloc d'un projet plus vaste, le super-radiotélescope appelé le Square Kilometre Array (SKA), qui sera composé de 3 000 antennes. Ce projet a été construit pour un coût de 51 millions de dollars australiens (soit environ 36 millions d'euros). Le MWA génère d'immenses quantités de données, récupérées sur les premières formations de galaxies. (fr) O Murchison Widefield Array (MWA) é um projeto conjunto entre universidades para construir um radiotelescópio de baixa frequência, operando na faixa de frequência de 80-300 MHz. Os principais objetivos científicos da MWA são para detectar emissão de hidrogênio atômico neutro da Época de Reionização (EoR), para estudar o Sol, a heliosfera, a Terra e a ionosfera. O custo total do projeto é de 51 milhões de dólares. (pt) |
