数据集中大量点源的存在会修改泊松分布的基本中微子计数统计数据。这种偏差可以用非泊松模板拟合技术精确地量化，在这项工作中，我们首次提出了这种方法在冰立方高能中微子数据集上的应用。使用这种方法，我们在7年的IceCube数据中搜索与银河系盘、费米气泡、Schleel、Finkbeiner和Davis尘埃图或与各向同性河外天空相关的点源群体。在使用这种技术的数据中没有发现这样一个总体的证据，并且在没有信号的情况下，我们建立了具有源-计数分布函数的总体模型的约束，该函数可以用带有单个中断的幂定律来描述。派生的限制可以在许多可能的源类的上下文中解释。为了增强结果的灵活性，我们公布了我们分析的完整后验结果，它可以用来对特定的种群模型建立限制，这些模型将对观测到的冰立方中微子通量做出贡献。
The presence of a population of point sources in a data set modifies the underlying neutrino-count statistics from the Poisson distribution. This deviation can be exactly quantified using the non-Poissonian template fitting technique, and in this work we present the first application of this approach to the IceCube high-energy neutrino data set. Using this method, we search in 7 yr of IceCube data for point-source populations correlated with the disk of the Milky Way, the Fermi bubbles, the Schlegel, Finkbeiner, and Davis dust map, or with the isotropic extragalactic sky. No evidence for such a population is found in the data using this technique, and in the absence of a signal, we establish constraints on population models with source-count distribution functions that can be described by a power law with a single break. The derived limits can be interpreted in the context of many possible source classes. In order to enhance the flexibility of the results, we publish the full posterior from our analysis, which can be used to establish limits on specific population models that would contribute to the observed IceCube neutrino flux.
