90 GHz Observations with the Green Bank Telescope

该项目将委托并使用宾州阵列接收器（PAR），这是一种新型64元辐射热计相机，专门设计用于100米格林班克望远镜（GBT），波长为3mm（频率为90GHz）。PAR本身已经由美国国家科学基金会通过其中心国家射电天文台资助。通过利用GBT的大采集面积，PAR将成为世界上最快、最灵敏的毫米波测绘阵列。示范科学项目涵盖范围很广，从太阳系到银河系再到宇宙结构（包括苏尼耶夫-泽尔多维奇效应和高红移星系）。随着端到端效率在未来几年内提高到3mm， PAR将采用分阶段的方法，从最有可能成功的观察开始，承担越来越多具有挑战性的项目。不可避免地，像这样的新能力将产生广泛但难以预料的影响。这个项目是使该仪器被尽可能多的天文学家使用的必要和关键的一步。该组织是由美国、波多黎各和墨西哥的机构组成的国际合作组织，知识、资源和学生的交流将有助于加强联系。

AST-0607654DevlinThis project will commission and use the Penn Array Receiver (PAR), a new 64-element bolometer camera, custom-designed for use on the 100m Green Bank Telescope (GBT) at a wavelength of 3mm (frequency 90GHz). The PAR itself is already funded by the NSF, through its center, the National Radio Astronomy Observatory. By taking advantage of the GBT's large collecting area, the PAR will be the fastest and most sensitive millimeter-wave mapping array in the world. Demonstration science projects cover a wide range, from the solar system to the Galaxy to cosmological structure (including the Sunyaev-Zel'dovich effect and high redshift galaxies). As the end-to-end efficiency increases at 3mm over the next few years, more and more challenging projects will be undertaken by the PAR, in a staged approach that starts with the observations most likely to be successful.Inevitably, a new capability such as this will have wide but hard-to-anticipate impacts. This project is a necessary and critical step towards making the instrument usable by the widest possible community of astronomers. The group is an international collaboration of institutions in the U.S., Puerto Rico, and Mexico, and the exchange of knowledge, resources and students will help to strengthen ties.
