The prime objective for the AMANDA/IceCube neutrino telescopes is to open a new observational window in astrophysics. The challenge is to measure high energy neutrinos of cosmic origin. Such observation would shed light on the mechanisms of acceleration of the highest energy cosmic rays and would allow a mapping of their sources. They might also provide essential insights regarding the origin of high-energy gamma rays. Apart from these astrophysics objectives, IceCube plans to investigate topics related to particle physics and cosmology, such as signatures of dark matter, extra dimensions, magnetic monopoles, as well as exotic superheavy objects like nuclearities or Q-balls. IceCube will also be sensitive to supernovae explosions within our galaxy. This proposal for an Emmy Noether grant aims to enhance the physics potential of IceCube, exploiting the energy region below 10 TeV. This energy corresponds to the low energy physics analysis threshold according to the current baseline design of IceCube. The central physics topic of this proposal is the search for astrophysical objects which emit neutrinos (i.e. point sources) in this energy band. Novel methods for improving the sensitivity for point sources below 10 TeV are proposed. This includes the development of a `low-energy¿ trigger, the improvement of the light collection efficiency of the optical modules of IceCube (photon sensors) and the use of space and time correlations (`multi-wavelength analysis¿) for transient neutrino candidate point sources.

阿曼达/IceCube中微子望远镜的主要目标是在天体物理学中打开一个新的观测窗口。挑战在于测量宇宙起源的高能中微子。这种观测将有助于了解最高能量宇宙射线加速的机制，并有助于绘制其来源的地图。它们还可能提供有关高能伽马射线起源的重要见解。除了这些天体物理学目标外，IceCube还计划研究与粒子物理学和宇宙学相关的主题，例如暗物质的特征，额外维度，磁单极子，以及像核或Q球这样的外来超重物体。冰立方也将对我们银河系内的超新星爆炸敏感。这项艾美奖Noether资助的提案旨在提高IceCube的物理潜力，利用低于10 TeV的能量区域。根据IceCube当前的基线设计，该能量对应于低能量物理分析阈值。这个提议的中心物理主题是寻找在这个能带中发射中微子（即点源）的天体。提出了提高10 TeV以下点源灵敏度的新方法。这包括开发一种“低能量”触发器，提高IceCube光学模块（光子传感器）的光收集效率，以及利用空间和时间相关性（“多波长分析”）研究瞬态中微子候选点源。
