在查南托天文台观测QUIET

查南托天文台,设施的技术加州理工学院(加州理工学院)的合作与智利大学和康塞普西翁大学经营,位于在智利北部安第斯山脉5080米(16700英尺)亚慱电竞的海拔。 The high, dry Chajnantor plateau is one of the best sites in the world for millimeter and submillimeter astronomy.

项目

安静

Q /ù成像实验(安静)开始于2008年10月作出的宇宙微波背景辐射的偏振观测。 A collaboration between experimental groups at Caltech, Chicago, Columbia, JPL, KEK, Manchester, MPIfR Bonn, Miami, Oslo, Oxford, Princeton, and Stanford, QUIET is a program to make very sensitive measurements of the polarization of the cosmic microwave background with large arrays of coherent correlation polarimeters. QUIET takes advantage of a breakthrough developed at JPL for the packaging of the polarimeters (“radiometer on a chip”) that allows their mass production so thousands of detectors can be used. In the first phase, two receivers have been constructed, one with 19 pixels at 44 GHz and another with 91 pixels at 90 GHz. A 1.4 m compact range antenna is attached to the CBI mount. The measurements cover angular scales from a few arc minutes to several degrees.

CBI

宇宙背景成像仪(CBI)是一个特殊用途的射电望远镜设计通过测量波动的强度和偏振在宇宙微波背景辐射研究早期宇宙。 It consisted of 13 Cassegrain antennas on a common platform, linked as an interferometer array, and received radiation in the 26–36 GHz band. It observed the microwave background, clusters of galaxies, and selected Galactic objects from 1999 to 2008.

教育和公众宣传

该查南托天文台正在开展积极的教育和圣佩德罗德阿塔卡马镇推广方案。 In this program, teachers from the San Pedro school visit the California Institute of Technology and the Jet Propulsion Laboratory in Pasadena, and they take short training courses at the Lewis Center for Educational Research in the Apple Valley. In these programs they are instructed in the use of newly-developed teachers' training tools, which they can then use in their classes in San Pedro to give their students direct access to and control of radio telescopes at Goldstone (GAVRT),并在欧文斯谷射电天文台。 The data from these observations are used in refereed scientific papers. In addition, astronomers from the Chajnantor Observatory give lectures to the local schools and host visits of classes to the observatory.

查南托该天文台的另一个重要方面是来自智利大学和大学去康塞普西翁,和两名学生目前正在做基于工作在天文台进行博士论文年级本科生和研究生的积极合作。亚慱电竞唯一官网
