ALFALFA: The Arecibo Extragalactic HI Legacy Survey

位于波多黎各的305米射电望远镜上的阿雷西博传统快速ALFA项目（“ALFA”是一种新型七波束射电相机的名称：阿雷西博l波段馈电阵列）是一项正在进行的尖端调查，将绘制整个天空的大约17%。在2010年完成后，大约20,000个银河系外的中性氢线源将被发现。这次调查是迄今为止在类似的天空区域进行的最深、最高分辨率的河外中性氢盲调查。首席研究员和他的团队领导调查，该调查以开放合作的方式组织，并基于实现最大的科学回报和最广泛的研究人员社区参与的原则。室女座星系团是调查区域的首要目标，这使得该项目可能更加有趣，因为它可能会发现重要的新结构。研究生参与项目的所有阶段，帮助规划和执行观测程序，开发数据处理和分析软件，生产公共数据产品，以及承担自己的科学项目。该小组将提供丰富而均匀的数据集，使尽可能广泛的社区能够进行许多应用，并与在其他波长进行的广域调查协同使用。

The Arecibo Legacy Fast ALFA project, ("ALFA" is the name of a new seven-beam radio camera: the Arecibo L-band Feed Array) at the 305-m radio telescope in Puerto Rico is an ongoing cutting-edge survey which will map approximately 17% of the entire sky. Upon its completion in 2010, approximately 20,000 extragalactic neutral-hydrogen line sources will be found. This survey is the deepest, highest resolution blind extragalactic neutral hydrogen survey ever conducted over a comparable area of the sky. The Principal Investigator and his team lead the survey, which is organized as an open collaboration and based on principles of enabling maximal scientific return and engaging the broadest community of researchers. The Virgo Cluster is a top target in the survey area, which makes the project potentially even more interesting as it is likely that important new structures may be found. Graduate students are involved in all phases of the project, helping to plan and execute the observing program, developing software for data processing and analysis, and producing public data products, as well as undertaking their own science projects. The group will provide a rich and homogeneous dataset, which enables many applications by the broadest possible community ans is useful in synergy with wide area surveys conducted at other wavelengths.
