This consolidated submission includes seven projects, mostly falling under astrophysical fluid dynamics (3 projects) or cosmology (3 projects). One additional project is on observations of active galactic nuclei and their impact on galaxy evolution and the interstellar medium. The number of projects submitted to this STFC round is one larger than last year, but that is because we have four new applicants, therefore, per academic FTE in the general area of astrophysics the number of projects has decreased. The research represents the traditional strengths of Newcastle Applied Mathematics in astrophysical fluid dynamics, including a project on Neutron Stars (which addresses STFC Big Science Question C: What are the basic constituents of matter as well as B: how do stars develop), one on massive stars (B: How do stars and planetary systems develop) and one on the interstellar medium (ISM, again B). The other three projects which revolve around cosmology all address the STFC Big Science Question A: How did the Universe begin and how is it evolving?). The research group is similarly made up of a combination of applied mathematicians who have been at Newcastle for some time and have applied to STFC in past rounds and a cohort of early career researchers hired recently as part of the renewed Newcastle Physics program.

这一合并提交的项目包括7个项目，主要属于天体物理流体动力学（3个项目）或宇宙学（3个项目）。另一个项目是观测活动星系核及其对星系演化和星际介质的影响。提交给这一轮STFC的项目数量比去年多一个，但这是因为我们有四个新的申请人，因此，在天体物理学的一般领域，每个学术FTE的项目数量有所减少。这项研究代表了纽卡斯尔应用数学在天体物理流体动力学方面的传统优势，包括一个关于中子星的项目（解决了STFC大科学问题C：物质的基本成分是什么以及B：恒星如何发展），一个关于大质量恒星（B：恒星和行星系统如何发展）和一个关于星际介质（ISM，再次B）。其他三个围绕宇宙学的项目都解决了STFC大科学问题A：宇宙是如何开始的，它是如何进化的？）。该研究小组同样由在纽卡斯尔工作了一段时间并在过去几轮中申请了STFC的应用数学家和最近作为更新的纽卡斯尔物理计划的一部分聘用的一批早期职业研究人员组成。
