This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). It will provide funds to pursue the analysis of IceCube data. IceCube is a high-energy neutrino telescope currently under construction at the South Pole. Half of the detector has been installed and is being operated. Once completed in 2011, the in-ice component will have a volume of one cubic kilometer. IceCube's main objective is the observation of high-energy neutrinos from astrophysical sources. It is strongly connected with other experiments in the field of astroparticle physics and its results can be used for a multi-messenger survey of the high-energy sky. The group plans to make contributions in three areas of research:1. Search for neutrinos in coincidence with gamma-ray bursts: detection would prove these objects to be the source of the highest energy cosmic rays. 2. Search for high-energy neutrinos from core collapse supernovae: a discovery would significantly enhance our understanding of supernovae.3. Observation of atmospheric neutrinos via the cascade channel: to date, high-energy atmospheric neutrinos have not yet been observed with the cascade channel. Increasing the detector size and improvements in reconstruction algorithms and background rejection techniques will allow IceCube to make this observation. The broader impacts of the program include activities involving elementary, middle and high schools particularly where a large fraction of the student body is of Latin-American descent.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。它将提供资金来分析IceCube数据。IceCube是目前正在南极建造的高能中微子望远镜。探测器已安装一半，正在运行。一旦在2011年完成，冰内组件的体积将达到一立方公里。IceCube的主要目标是观测来自天体物理源的高能中微子。它与天体粒子物理学领域的其他实验密切相关，其结果可用于高能天空的多信使观测。该小组计划在三个研究领域做出贡献：1。寻找与伽马射线爆发同时发生的中微子：探测将证明这些物体是最高能量宇宙射线的来源。2.从核心坍缩超新星中寻找高能中微子：这一发现将大大增强我们对超新星的理解。通过级联通道观测大气中微子：迄今为止，尚未通过级联通道观测到高能大气中微子。增加探测器的尺寸，改进重建算法和背景抑制技术，将使IceCube能够进行这种观察。该方案的更广泛影响包括涉及小学、初中和高中的活动，特别是在大部分学生是拉丁美洲后裔的地方。
