标题： Anisotropies in the diffuse gamma-ray background measured by the Fermi-LAT

摘要： unresolved来源对弥散伽马射线背景的贡献可能在此辐射在小角尺度上产生各向异性。 近期的研究已经将角功率谱和其他各向异性度量作为工具，用以识别弥散发射来自未分辨源类（如河外和银河系暗物质以及各种天体物理伽马射线源群体）的贡献。 我们展示了由Fermi-LAT测量到的弥散发射的各向异性分析的初步结果。 显示英文摘要

摘要： The contribution of unresolved sources to the diffuse gamma-ray background could produce anisotropies in this emission on small angular scales. Recent studies have considered the angular power spectrum and other anisotropy metrics as tools for identifying contributions to diffuse emission from unresolved source classes, such as extragalactic and Galactic dark matter as well as various astrophysical gamma-ray source populations. We present preliminary results of an anisotropy analysis of the diffuse emission measured by the Fermi-LAT.
