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.

位于波多黎各的305米射电望远镜上的阿雷西博遗产快速ALFA项目（“ALFA”是一种新的七波束射电相机的名称：阿雷西博L波段馈源阵列）是一项正在进行的尖端调查，将绘制整个天空的约17%。在2010年完成后，将发现大约20，000个河外中性氢线源，这是迄今为止在天空可比区域进行的最深、分辨率最高的河外中性氢盲测。首席研究员及其团队领导了这项调查，该调查是以开放式合作的方式组织的，并基于实现最大科学回报和吸引最广泛的研究人员社区的原则。室女座星系团是调查区域的首要目标，这使得该项目可能会更加有趣，因为它很可能会发现重要的新结构。研究生参与了项目的所有阶段，帮助计划和执行观测计划，开发数据处理和分析软件，制作公共数据产品，以及承担自己的科学项目。该小组将提供一个丰富和同质的数据集，使许多应用程序的最广泛的社区，是有用的协同作用，在其他波长进行广域调查。
