90 GHz Observations with the Green Bank Telescope

AST-0607654 Devlin该项目将调试和使用Penn阵列接收器（PAR），这是一种新的64元件测辐射热仪相机，为100米绿色银行望远镜（GBT）定制设计，波长为3毫米（频率为90 GHz）。 PAR本身已经由NSF通过其中心国家射电天文台资助。 通过利用GBT的大收集面积，PAR将成为世界上最快和最灵敏的毫米波测绘阵列。 示范科学项目涵盖范围广泛，从太阳系到银河系再到宇宙学结构（包括Sunyaev-Zel'dovich效应和高红移星系）。 随着端到端效率在未来几年内以3 mm的速度增长，PAR将以分阶段的方式开展越来越多具有挑战性的项目，从最有可能成功的观测开始。不可避免地，这样的新能力将产生广泛但难以预料的影响。 该项目是使该仪器为尽可能广泛的天文学家使用的必要和关键的一步。 该组织是一个国际合作机构在美国，波多黎各和墨西哥，以及知识、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.
