冰立方中微子望远镜的点源搜索仅限于一个半球，这是由于专门选择向上的事件作为拒绝大气μ子背景的一种方式。我们表明，地平线以上的区域可以包括通过能量敏感削减抑制背景。这提高了PeV能量以上的灵敏度，以前由于地球对中微子的吸收，在视界以下几度以上的赤纬是无法获得的。我们目前的结果的基础上收集的数据与22串冰立方，扩展其视野和能源范围的点源搜索。在天空扫描和候选源测试中没有观察到大气背景以上的显著过量。上限的报告，这是第一次覆盖点源在南部天空高达EeV的能量。
Point source searches with the IceCube neutrino telescope have been restricted to one hemisphere, due to the exclusive selection of upward going events as a way of rejecting the atmospheric muon background. We show that the region above the horizon can be included by suppressing the background through energy-sensitive cuts. This improves the sensitivity above PeV energies, previously not accessible for declinations of more than a few degrees below the horizon due to the absorption of neutrinos in Earth. We present results based on data collected with 22 strings of IceCube, extending its field of view and energy reach for point source searches. No significant excess above the atmospheric background is observed in a sky scan and in tests of source candidates. Upper limits are reported, which for the first time cover point sources in the southern sky up to EeV energies.
