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。他们追踪星际介质，并为重力提供了重要的压力支撑来源，这将减慢将气体转化为恒星的过程。了解领域的发展及其真正的动态重要性仍然是一个尚未解决的问题，但这对于我们对Galaxy Evolution以及Star和Planet形成的理解至关重要。在这个项目中，我们将使用有史以来执行的银河系磁场的一些最高分辨率模拟，并将其放大到更详细的内容，以研究磁场如何影响气体的冷分子云的形成，它们形成恒星的效率以及其中恒星的分布。在此项目中，您将使用Dirac Super Cromputing设施进行高级HPC模拟，作为P.I的“缩放到星形组”主题项目的一部分。数据分析将主要在Python中使用该组中编写的脚本进行，但也由学生开发。然后，我们的结果将与Sophia Fieldmaps调查，偏光粉尘图和HI观测值的观察结果进行严格的比较。关于基本编程的一些知识，尤其是在Python中，是可取的，但是将作为博士学位的一部分提供培训。
