CRPropa 3 --一个用于解释地外超高能粒子的公共天体物理模拟框架
CRPropa 3 - a Public Astrophysical Simulation Framework for Propagating Extraterrestrial Ultra-High Energy Particles
摘要：
我们提出的模拟框架CRPropa第3版设计的超高能粒子的天体物理预测的有效发展。用户可以组装银河系和河外空间中最相关的传播效应模块，包括具有新功能的自己的物理模块，并接收输出的初级和次级宇宙信使，包括原子核，中微子和光子。在扩展到包含在以前的CRPropa版本的传播物理，新版本促进高性能计算，并包括新的物理功能，如界面的星系传播使用透镜技术，改进的光核相互作用计算，并在时间依赖的环境中传播，以考虑到宇宙演化的影响，在各向异性研究和变量源。第一个应用程序使用突出显示的功能，以及提出。
英文摘要：
We present the simulation framework CRPropa version 3 designed for efficient development of astrophysical predictions for ultra-high energy particles. Users can assemble modules of the most relevant propagation effects in galactic and extragalactic space, include their own physics modules with new features, and receive on output primary and secondary cosmic messengers including nuclei, neutrinos and photons. In extension to the propagation physics contained in a previous CRPropa version, the new version facilitates high-performance computing and comprises new physical features such as an interface for galactic propagation using lensing techniques, an improved photonuclear interaction calculation, and propagation in time dependent environments to take into account cosmic evolution effects in anisotropy studies and variable sources. First applications using highlighted features are presented as well.
