IceCube -天体物理学和天体粒子物理学在South Pole

IceCube - Astrophysics and Astroparticle Physics at the South Pole

The IceCube Collaboration

摘要:

南极冰立方中微子观测站已于2010年12月建成。在本文中,我们描述了最终的检测器和报告结果的物理和性能使用的数据在不同阶段的尚未完成的检测器。目前还没有发现宇宙中微子的点源和扩散流信号,并讨论了这些研究的前景,包括建立多信使计划。伽玛射线暴对中微子的限制远低于模型预测,需要重新评估伽玛射线暴模型的假设。从大气μ子和中微子谱以及从空气簇射测量中获得了宇宙射线特性的各种测量结果;这些结果将对模型的发展产生重要影响。冰立方在多个角度尺度上观察到宇宙射线的各向异性,这是第一次在南部天空中观察到。IceCube的独特能力,监测瞬态低能量事件进行了简要讨论。最后展望了计划中的扩展,这将提高低能量和高能量侧的灵敏度。

英文摘要:

The IceCube Neutrino Observatory at the South Pole has been completed in December 2010. In this paper we describe the final detector and report results on physics and performance using data taken at different stages of the yet incomplete detector. No signals for cosmic neutrinos from point sources and diffuse fluxes have been found. Prospects of these searches, including the setup of multi-messenger programs, are discussed. The limits on neutrinos from GRBs, being far below model predictions, require a reevaluation of GRB model assumptions. Various measurements of cosmic ray properties have been obtained from atmospheric muon and neutrino spectra and from air shower measurements; these results will have an important impact on model developments. IceCube observed an anisotropy of cosmic rays on multiple angular scales, for the first time in the Southern sky. The unique capabilities of IceCube for monitoring transient low energy events are briefly discussed. Finally an outlook to planned extensions is given which will improve the sensitivities both on the low and high energy side.
