The proposed research programme in astronomy theory at Newcastle University includes six projects. Their unifying theme is the focus on hydrodynamic (HD) and magnetohydrodynamic (MHD) processes, ranging in scale from stars to the large-scale cosmological structure. Newcastle is an internationally leading research centre in the area of astrophysical HD and, especially, MHD. The proposed research involves a wide range of physical processes and a wide range of models and tools, including effective field theory models in cosmology, and analytical MHD models and state-of-the-art numerical simulations for a range of astrophysical objects in a variety of geometries. All of the proposed work also includes extensive comparisons with the latest observations.The proposed programme will contribute to several research areas of strategic importance, including problems identified inSTFC's Big Questions of Science Roadmap:A:2 How did structure first form? (Project 4: Psi in the sky: Dark Matter as a light scalar, Project 6: Magnetic fields in the cosmic web)A:3 What are the roles of dark matter and dark energy? (Project 4)A:5 How do galaxies evolve? (Project 1: New methods for exploiting broadband radio-polarimetry, Project 3: A new generation of semi-analytic galaxy formation models., and Project 5: Internal gravity waves in evolved, intermediate mass stars)A:6 How do stars form and how do they evolve? (Project 2: Superfluid dynamics in neutron stars and Project 5)D:1 How do the laws of physics work when driven to the extremes? (Project 2)D:2 How can high energy particles and gravitational waves tell us about the extreme universe? (Project 3)D:3 How do ultra-compact objects form, what is their nature and how does extreme gravity impact on their surroundings? (Project 2)

拟议中的纽卡斯尔大学天文学理论研究方案包括六个项目。他们的统一主题是集中在流体动力学（HD）和磁流体动力学（MHD）过程，范围从恒星到大尺度宇宙结构。纽卡斯尔是天体物理HD领域的国际领先研究中心，尤其是MHD。拟议的研究涉及广泛的物理过程和广泛的模型和工具，包括宇宙学中的有效场论模型，以及各种几何形状的一系列天体物理对象的分析MHD模型和最先进的数值模拟。所有拟议的工作还包括与最新观测结果的广泛比较。拟议的计划将有助于几个具有战略重要性的研究领域，包括STFC的科学路线图的大问题中确定的问题：A：2结构是如何形成的？（项目4：天空中的PSI：暗物质作为光标量，项目6：宇宙网络中的磁场）答：3暗物质和暗能量的作用是什么？（项目4）A：5星系是如何演化的？（项目1：利用宽带无线电偏振测量的新方法，项目3：新一代半解析星系形成模型。和项目5：演化中的中等质量恒星的内部重力波）A：6恒星是如何形成的，它们是如何演化的？（项目2：中子星中的超流体动力学和项目5）D：1物理定律在极端情况下如何工作？（项目2）D：2高能粒子和引力波如何告诉我们极端宇宙的情况？（项目3）D：3超紧凑物体是如何形成的，它们的性质是什么，极端重力如何影响它们的周围环境？（项目二）
