论文摘要
Messenger接口Monte-Carlo Mappings V（M^3）是采用完全自洽的蒙特卡罗辐射转移技术的光电离代码，该技术对先前具有简单几何形状的光电离电模型提出了重大进步。 M^3设计用于在任意三维几何形状中对星云进行建模。在本文中，我们描述了M^3中实施的蒙特卡罗辐射转移技术和微物理学，包括光电离，碰撞电离，自由和自由结合的重组和两光子辐射。我们通过Lexington/Meudon基准测试M^3，以测试新代码的可靠性。我们将M^3至三个具有基准几何形状的HII区域模型应用，这表明M^3能够与复杂的几何形状处理星云。 M^3是一种有前途的工具，用于了解SDSS-V/LVM和JWST时代的发射线行为，该行为将提供附近HII区域的空间分辨的高质量数据以及高度湍流的局部和高度降低的HII区域。
The Messenger Interface Monte-Carlo Mappings V (M^3) is a photoionization code adopting the fully self-consistent Monte-Carlo radiative transfer technique, which presents a major advance over previous photoionization models with simple geometries. M^3 is designed for modeling nebulae in arbitrary three-dimensional geometries. In this paper, we describe the Monte-Carlo radiative transfer technique and the microphysics implemented in M^3, including the photoionization, collisional ionization, the free-free and free-bound recombination, and two-photon radiation. We put M^3 through the Lexington/Meudon benchmarks to test the reliability of the new code. We apply M^3 to three HII region models with fiducial geometries, demonstrating that M^3 is capable of dealing with nebulae with complex geometries. M^3 is a promising tool for understanding emission-line behavior in the era of SDSS-V/LVM and JWST, which will provide high-quality data of spatially-resolved nearby HII regions and highly turbulent local and high-redshift HII regions.
