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)

纽卡斯尔大学天文学理论的拟议研究计划包括六个项目。他们统一的主题是关注流体动力学（HD）和磁性水力动力学（MHD）过程，从恒星到大规模宇宙学结构的规模不等。纽卡斯尔（Newcastle）是天体物理高清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以及各种模型和工具，包括宇宙学中的有效现场理论模型，分析性MHD模型和最新的数值模拟，用于各种几何形状中的一系列天体物理对象。所有拟议的工作还包括与最新观察结果的广泛比较。拟议的计划将有助于几个战略重要性的研究领域，包括确定Instfc的《科学路线图》的问题：a：2结构是如何首先形式的？ （项目4：天空中的PSI：暗物质作为轻标量，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星系如何发展？ （项目1：用于利用宽带无线电极化的新方法，项目3：新一代的半分析星系形成模型。 （项目2：中子星和项目5中的超氟动力学）D：1 1当物理定律驱动到极端时如何起作用？ （项目2）D：2高能量颗粒和重力波如何告诉我们极端宇宙？ （项目3）d：3超紧凑型物体如何形成，它们的性质是什么，极端重力对周围环境有何影响？ （项目2）
