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对抗重力的重要压力支持源，这将减缓气体转变为恒星的过程。了解场如何演化及其真正的动态重要性仍然是一个悬而未决的问题，但这对于我们理解星系演化以及恒星和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，并进行更详细的研究，以研究磁场如何影响气体冷分子云的形成、它们形成恒星的效率以及分布其中的星星。在此项目中，您将使用 DiRAC 超级计算设施进行高级 HPC 模拟，作为 P.I 的“放大恒星形成”主题项目的一部分。数据分析将主要使用Python进行，使用小组内已经编写的脚本，但也由学生开发。然后，我们的结果将与 SOPHIA FIELDMAPS 调查、偏振尘埃图和 HI 观测的观测结果进行严格比较。需要一些基本编程知识，特别是 Python 知识，但培训将作为博士学位的一部分提供。
