用IceCube望远镜进行中微子搜索

Neutrino searches with the IceCube telescope

Juan A. Aguilar

摘要:

冰立方中微子观测站是一个由5,160个光电倍增管(PMT)组成的阵列,部署在南极冰层内1.5-2.5公里深处的86根弦上。冰立方实验的主要目标是探测天体物理学中微子信号。在这篇文章中,我们提出了从2008年4月到2011年5月的数据点源分析的结果,当三个探测器配置操作:40串配置(IC-40),59串配置(IC-59)和79串配置(IC-79)。没有显着过量指示点源的中微子已被发现,我们提出的上限为$E^{-2}$ μ子中微子通量的候选来源列表。在天空的某些部分,这些极限第一次开始达到$10^{-12}$ TeV $^{-1}$ cm $^{-2}$ s $^{-1}$。

英文摘要:

The IceCube Neutrino Observatory is an array of 5,160 photomultipliers (PMTs) deployed on 86 strings at 1.5-2.5 km depth within the ice at the South Pole. The main goal of the IceCube experiment is the detection of an astrophysical neutrino signal. In this contribution we present the results of the point source analysis on the data taken from April 2008 to May 2011, when three detector configurations were operated: the 40-string configuration (IC-40), the 59-string configuration (IC-59) and the 79-string configuration (IC-79). No significant excess indicative of point sources of neutrinos has been found, and we present upper limits for an $E^{-2}$ muon neutrino flux for a list of candidate sources. For the first time these limits start to reach $10^{-12}$ TeV$^{-1}$ cm$^{-2}$ s$^{-1}$ in some parts of the sky.
