clumpy: A code for γ-ray signals from dark matter structures

Abstract
We present the first public code for semi-analytical calculation of the γ-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 ca...

Title of program: CLUMPY
Catalogue Id: AEKS_v1_0

Nature of problem
Calculation of γ-ray signal from dark matter annihilation (resp. decay). This involves a particle physics term and an astrophysical one. The focus here is on the latter.

摘要
本报告首次公开了半解析计算银河系中暗物质湮灭/衰变所致的γ射线通量天体物理J因子的代码。代码的核心在于计算暗物质密度平方（湮灭情况）或密度（衰变暗物质）的视线积分。本代码支持三种使用模式：i) 从银河系光滑成分及/或子结构贡献绘制天图，ii) 进行计算……
