CLUMPY v3: gamma-ray and neutrino signals from dark matter at all scales

We present the third release of the CLUMPY code for calculating gamma-ray and neutrino signals from annihilations or decays in dark matter structures. This version includes the mean extragalactic signal with several pre-defined options and keywords related to cosmological parameters, mass functions for the dark matter structures, and gamma-ray absorption up to high redshift. For more flexibility and consistency, dark matter masses and concentration are now defined with respect to a user-defined overdensity Delta. We have also made changes for the user’s benefit: distribution and versioning of the code via git, less dependencies and a simplified installation, better handling of options in run command lines, consistent naming of parameters, and a new Sphinx documentation at http://lpsc.in2p3.fr/clumpy/.

我们发布了CLUMPY代码的第三个版本，该代码用于计算暗物质结构内粒子湮灭或衰变产生的伽马射线与中微子信号。本版本包含平均河外信号，预设多项与宇宙学参数、暗物质结构质量函数相关的选项及关键词，并支持高红移处的伽马射线吸收效应计算。为兼顾灵活性与一致性，暗物质的质量与浓度现均以用户自定义的过密度Delta为基准进行定义。我们还针对用户体验进行了多项优化：通过Git实现代码的分发与版本管理，缩减了依赖项并简化了安装流程，优化了运行命令行的选项处理逻辑，统一了参数命名规范，并新增了基于Sphinx的官方文档，网址为http://lpsc.in2p3.fr/clumpy/。
