项目摘要

Each new generation of stars in our own and other galaxies contributes to the enrichment of the interstellar medium (ISM) in heavy elements. Over time, these heavy elements, which may be injected as gas or dust particles, and the outflows that carry them, progressively modify the way that new stars and planets form, as well as the overall properties of the galaxies themselves. Gaining a greater understanding of star formation and the ISM evolution of galaxies, and their interplay, has provided the motivation for the construction of a large number of international facilities, including the VLT, ALMA, the Spitzer Space Telescope, the Herschel Space Observatory and the James Webb Space Telescope. These missions will give us access to observations of unprecedented spatial and spectral resolution. Due to these dramatic observational advances, there is a distinct need for theoretical tools that will allow us to correctly interpret the wealth of observational data that we will receive: the research outlined in this proposal aims to provide the community with a state-of-the-art self-consistent 3-dimensional radiative transfer and chemical modelling tool which will be able to simulate and fit multi-wavelength photometric and spectroscopic high resolution data from star forming regions in our own and other galaxies. The products of this plan of research will form an essential part of the preparatory science for upcoming missions, such as Herschel, ALMA and the JWST.

每个新一代的恒星和其他星系都在沉重的元素中促进了星际介质（ISM）的富集。随着时间的流逝，这些重型元素可能被注射为气体或灰尘颗粒，以及携带它们的流出，逐渐改变了新恒星和行星形成的方式，以及星系本身的整体特性。对星系的恒星形成和ISM的进化有了更深入的了解，以及它们的相互作用，为建造大量国际设施提供了动力，包括VLT，ALMA，Spitzer太空望远镜，Herschel Space Pastervatory和James Webb太空望远镜。这些任务将使我们访问前所未有的空间和光谱分辨率的观察。由于这些戏剧性的观察进步，理论上的工具有明显的需求，使我们能够正确解释我们将收到的大量观察数据：本提案中概述的研究旨在为社区提供最先进的自伴随的3维辐射转移和化学模型工具，从而可以从高高和拟合型号的数据范围内进行模拟和拟合长度的数据，从而能够模拟良好的良好型孔的启示，并启用了良好的良好的良好的良好的良好的启示式启示式构想，并构成了良好的良好的启示范围的繁荣构图。拥有和其他星系。该研究计划的产品将成为即将到来的任务的预备科学的重要组成部分，例如Herschel，Alma和JWST。
