标题： CLUMPY: a code for gamma-ray signals from dark matter structures

摘要： 我们提供了首个公开代码，用于从银河系中暗物质湮灭/衰变产生的伽马射线流量天体物理J因子的半解析计算，包括暗物质子结构。 该代码的核心是计算暗物质密度平方的视线积分（对于湮灭）或密度（对于衰变）。 该代码可以有三种使用模式：i) 从银河系平滑成分和/或子结构贡献绘制天空图，ii) 计算特定晕（即不是银河晕，例如矮椭球星系）的流量，iii) 对于给定物体，从允许的DM分布列表中执行简单的统计操作。 银河系外贡献和其他DM湮灭示踪物（例如正电子、反质子）将在第二次发布中包含。 显示英文摘要

摘要： We present the first public code for semi-analytical calculation of the gamma-ray flux astrophysical J-factor from dark matter annihilation/decay in the Galaxy, including dark matter substructures. The core of the code is the calculation of the line of sight integral of the dark matter density squared (for annihilations) or density (for decaying dark matter). The code can be used in three modes: i) to draw skymaps from the Galactic smooth component and/or the substructure contributions, ii) to calculate the flux from a specific halo (that is not the Galactic halo, e.g. dwarf spheroidal galaxies) or iii) to perform simple statistical operations from a list of allowed DM profiles for a given object. Extragalactic contributions and other tracers of DM annihilation (e.g. positrons, antiprotons) will be included in a second release.
