This award provides continued funding for the UW-Madison group's scientific analysis of data collected with the South Pole IceCube neutrino observatory. IceCube will reach a total exposure of a km-squared-year of data within one year, a target neutrino astronomy has aspired to since the nineteen seventies. If typical estimates of their flux are valid, they will reach the sensitivity to observe the flux of cosmogenic neutrinos produced by the interactions of cosmic rays with microwave photons. If gamma ray bursts accelerate the observed extragalactic cosmic rays, they will detect the neutrinos produced when the protons and photons coexist in the fireball. The group participates in all major scientific analyses; in this project they emphasize that their goal is to not only increase statistics and better understand the systematics of the detector, but to focus on improvements of the analysis methods made possible by a larger and better instrument. UW-Madison scientists contribute on average half of their time to service tasks required to maintain and operate the detector. IceCube will undoubtedly enter a phase of modifications and enhancements of capabilities resulting from experience operating the detector and from new science opportunities. The group actively participates in the R&D program that capitalizes on the current IceCube scientific program. The radio detection of ultra high-energy neutrinos is the main focus at this time.Broader Impacts: The mystique of the South Pole environment and the compelling science are an alluring mix. The results of IceCube science will enhance scientific and technological understanding on many levels through broad dissemination of the results and experiences. IceCube is in a unique class of projects that inspire the innovative capacity of a new generation of American scientists and engineers.

该奖项为威斯康星大学麦迪逊分校对南极冰立方中微子观测站收集的数据进行科学分析提供了持续的资金。冰立方将在一年内达到一平方公里年的数据总曝光量，这是中微子天文学自20世纪70年代以来一直渴望的目标。如果对它们通量的典型估计是有效的，它们将达到观测宇宙射线与微波光子相互作用产生的宇宙成因中微子通量的灵敏度。如果伽马射线暴加速了观测到的河外宇宙射线，它们将探测到质子和光子在火球中共存时产生的中微子。该小组参与所有主要的科学分析;在这个项目中，他们强调，他们的目标不仅是增加统计数据和更好地了解探测器的系统，而且重点是通过更大更好的仪器来改进分析方法。威斯康星大学麦迪逊分校的科学家平均贡献一半的时间来维护和操作探测器所需的服务任务。毫无疑问，IceCube将进入一个修改和增强功能的阶段，这些功能来自操作探测器的经验和新的科学机会。该集团积极参与利用当前IceCube科学计划的研发计划。超高能中微子的无线电探测是目前的主要焦点。更广泛的影响：南极环境的神秘性和引人注目的科学是一个诱人的组合。冰立方科学的成果将通过广泛传播成果和经验，在许多层面上加强对科学和技术的理解。IceCube是一个独特的项目，激发了新一代美国科学家和工程师的创新能力。
