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.

该合并提交的提交包括七个项目，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）。另一个项目是观察活性银河核及其对星系进化和星际介质的影响。提交给STFC回合的项目数量比去年大，但这是因为我们有四个新申请人，因此，根据天体物理学一般领域的学术FTE，项目数量减少了。这项研究代表了纽卡斯尔在天体物理流体动力学中应用数学的传统优势，包括一个关于中子星星的项目（解决STFC大科学问题C：物质的基本组成部分以及b：恒星的发展是什么），一个在巨大的星星上（b：b：b：start and planetare system in of start and planetare system in of startary system in of the stheptellar in the stheptellar媒介）（isseltellar Medif）（issseltellar Medif）（isseltellar Medif）（isseltellar Medif）（ISSM）（ISM），b）。围绕宇宙学的其他三个项目都解决了STFC大科学问题A：宇宙是如何开始的，它如何发展？）。研究小组类似地是由纽卡斯尔（Newcastle）曾在纽卡斯尔（Newcastle）曾在纽卡斯尔（Newcastle）申请的应用数学家的组合组成的，并且在过去的回合中申请了STFC，最近聘请了许多早期职业研究人员作为新纽卡斯尔物理学计划的一部分。
