The Erciyes University Radio Observatory ((トルコ語: Erciyes Üniversitesi Radyo Astronomi Gözlemevi)) (ERAG) is a radio astronomy observatory operated by the Astronomy and Space Sciences Department at Erciyes University's Faculty of Science. It is located within university's campus at Melikgazi, Kayseri in central Turkey. Observatory's first radio telescope was a parabolic antenna of diameter, which was donated by the Marmara Research Center (MAM) of Scientific and Technological Research Council of Turkey (TÜBİTAK). The radio telescope, then called MRT-2, was initially purchased from the Institute of Radio Astronomy in Kharkiv, Ukraine with the financial help of UNIDO in 1996. Built to operate in the radio frequency range of 85-115 GHz, it was intended for the acquisition of carbon monoxide data in the Milky Way. In 1997, the telescope became inoperable, and the Ukrainian technicians were unavailable for its reparature. After some unsuccessful attempts to fix the radio telescope at site, it was handed over in 2000 to Erciyes University, where its rehabilation was carried out between 2001-2002. The next radio telescopes were two parabolic antennas of diameter (ERT-5), which were donated from the local branch office of Türk Telekom in 2000. They are part of a project to build an astronomical interferometer. The radio telescopes operate in the frequencies of 4.5, 11 and 20 GHz. In addition, a diameter antenna is situated at the site as well.〔 Further radio telescopes installed at the observatory are a antenna and a radome, both donated by NATO SATCOM.〔 Currently, the observatory operates the single-dish Cassegrain focus radio telescope inside the radome, the two ERT-5 and two optical reflecting telescopes of and diameter. Observatory's staff consists of five researchers and three assistants. == References == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Erciyes University Radio Observatory」の詳細全文を読む スポンサード リンク
