Magnetic fields pervade galaxies. They trace the interstellar medium and provide an important source of pressure support against gravity that will slow the process of transforming gas into stars. Understanding how fields evolve, and their true dynamic importance is still an unresolved question, but it is crucial for our understanding of both galaxy evolution and star and planet formation. In this project we will use some of the highest resolution simulations of galactic magnetic fields ever performed and zoom into even more detail to investigate how magnetic fields affect the formation of cold molecular clouds of gas, the efficiency with which they form stars, and the distribution of stars within them. In this project you will use the DiRAC supercomputing facility to carry out advanced HPC simulations as part of the P.I's "Zooming into Star Formation" thematic project. Data analysis will be mainly carried out in python, using scripts already written within the group, but also developed by the student. Our results will then be critically compared with observations from the SOPHIA FIELDMAPS survey, polarised dust maps, and HI observations. Some knowledge of basic programming, particularly in python, would be desirable but training will be provided as part of the PhD.

磁场遍布星系。它们追踪星际介质，并提供一个重要的压力来源，以对抗重力，这将减缓气体转化为恒星的过程。理解场是如何演化的，以及它们真正的动力学重要性仍然是一个悬而未决的问题，但它对我们理解星系演化和星星与行星的形成至关重要。在这个项目中，我们将使用一些有史以来最高分辨率的银河磁场模拟，并放大到更详细的研究磁场如何影响冷气体分子云的形成，它们形成恒星的效率，以及恒星在其中的分布。在这个项目中，你将使用DiRAC超级计算设备来进行高级HPC模拟，作为P.I的“放大星星形成”专题项目的一部分。数据分析将主要在python中进行，使用小组内已经编写的脚本，但也由学生开发。然后，我们的结果将严格比较SOPHIA FIELDMAPS调查，偏振尘埃图，HI观测观测。一些基本的编程知识，特别是Python，将是可取的，但培训将作为博士学位的一部分提供。
