论文摘要
在最近几年中，已经开发了具有非殖民运输的银河宇宙射线运输模型。该设置旨在重现银河系不同区域中的伽马射线观测（特别关注内部星系中的Hadroonic光谱的进行性硬化），并且被证明与最近检测到PEV Entergies的非常高的Energy Gamma-ray弥漫性发射兼容。在这项工作中，我们扩展了先前提出的结果，以测试该模型在整个天空中的可靠性。为此，我们将预测与Fermi-Lat测得的弥漫性伽马射线发射的详细经度和纬度曲线进行了比较，并计算了预期的银河中微子弥漫性发射，将其与Antares协作的当前限制进行了比较。我们强调，可能检测出银河中微子组件将使我们能够打破模型与其他场景之间的堕落性，这些场景具有未解决的来源和TEV Halos的突出贡献。
A Galactic cosmic-ray transport model featuring non-homogeneous transport has been developed over the latest years. This setup is aimed at reproducing gamma-ray observations in different regions of the Galaxy (with particular focus on the progressive hardening of the hadronic spectrum in the inner Galaxy) and was shown to be compatible with the very-high-energy gamma-ray diffuse emission recently detected up to PeV energies. In this work, we extend the results previously presented to test the reliability of that model throughout the whole sky. To this aim, we compare our predictions with detailed longitude and latitude profiles of the diffuse gamma-ray emission measured by Fermi-LAT for different energies and compute the expected Galactic neutrino diffuse emission, comparing it with current limits from the ANTARES collaboration. We emphasize that the possible detection of a Galactic neutrino component will allow us to break the degeneracy between our model and other scenarios featuring prominent contributions from unresolved sources and TeV halos.
