IceCube中微子望远镜点源探测的最新结果

Recent Results of Point Source Searches with the IceCube Neutrino Telescope

Erik Strahler

摘要:

冰立方是一个千米^3尺度的中微子探测器,正在南极冰层深处建造。完成后,IceCube将由4800个光学模块组成,部署在1450至2450米深度的80个字符串上。在2007-2008年的数据采集季节,有22个字符串运行。这种配置已经比以前的中微子望远镜大得多,并且对高能(>1 TeV)中微子发射的点源提供了更好的灵敏度。这样的天体是加速宇宙射线的主要候选者。我们描述了冰立方探测器,并介绍了最近几次搜索稳定(如AGN)和瞬态(GRB)点源的方法和结果。

英文摘要:

IceCube is a km^3 scale neutrino detector being constructed deep in the Antarctic ice. When complete, IceCube will consist of 4800 optical modules deployed on 80 strings between 1450 and 2450 m of depth. During the 2007-2008 data taking season, 22 strings were operational. This configuration is already much larger than previous neutrino telescopes and provides better sensitivity to point sources of high energy (>1 TeV) neutrino emission. Such astrophysical objects are leading candidates for the acceleration of cosmic rays. We describe the IceCube detector and present the methods and results of several recent searches for steady (e.g. AGN) and transient (GRB) point sources.
