我们描述了均匀分布的相对论电子和质子的非热光子发射模型。来自同步加速器、逆康普顿、非热韧致辐射和中性介子衰变过程的贡献分别使用非热粒子基本分布的共同参数进行了计算。这些模型旨在用于从多波长观测中拟合光谱,并被设计为准确和高效。尽管我们的应用程序专注于银河超新星遗迹,但该软件是模块化的,因此可以直接针对不同的应用程序进行定制。具体地,逆康普顿模型使用的粒子分布函数的形状和种子光子谱的形状在单独的模块中定义,并且可以为特定的应用定制。我们通过使用递推关系,并将它们与解析结果和其他作者以前的数值工作进行比较,来评估这些模型的精度。
We describe models of nonthermal photon emission from a homogeneous distribution of relativistic electrons and protons. Contributions from the synchrotron, inverse Compton, nonthermal bremsstrahlung, and neutral-pion decay processes are computed separately using a common parameterization of the underlying distribution of nonthermal particles. The models are intended for use in fitting spectra from multiwavelength observations and are designed to be accurate and efficient. Although our applications have focused on Galactic supernova remnants, the software is modular, making it straightforward to customize for different applications. In particular, the shapes of the particle distribution functions and the shape of the seed photon spectrum used by the inverse Compton model are defined in separate modules and may be customized for specific applications. We assess the accuracy of these models by using a recurrence relation and by comparing them with analytic results and with previous numerical work by other authors.
