本文介绍了用于计算尘埃辐射传输的并行、免费蒙特卡罗程序SUNRISE。SUNRISE采用自适应网格细化网格来描述发射和吸收/散射介质的任意几何形状，其空间动态范围超过104，可以高效地生成空间任意点的新兴辐射图像。除了蒙特卡罗编码通常使用的单色辐射传输外，SUNRISE还能够同时传播一系列波长。当计算光谱特征时，这种“多色”算法显著提高了效率和准确性。SUNRISE用于研究相互作用星系流体动力学模拟中尘埃的影响，并描述了这一过程。代码将根据先前发布的结果进行测试。
This paper describes SUNRISE, a parallel, free Monte Carlo code for the calculation of radiation transfer through astronomical dust. SUNRISE uses an adaptive mesh refinement grid to describe arbitrary geometries of emitting and absorbing/scattering media, with spatial dynamical range exceeding 10 4 , and it can efficiently generate images of the emerging radiation at arbitrary points in space. In addition to the monochromatic radiative transfer typically used by Monte Carlo codes, SUNRISE is capable of propagating a range of wavelengths simultaneously. This 'polychromatic' algorithm gives significant improvements in efficiency and accuracy when spectral features are calculated. SUNRISE is used to study the effects of dust in hydrodynamic simulations of interacting galaxies, and the procedure for this is described. The code is tested against previously published results.
