Explaining how galaxies form and evolve is one of the biggest challenges in astrophysics. From the black holes that lie in their hearts, to the dark matter than enshrouds them, galaxies are complex. Only by exploiting all the observational tools at our disposal can we hope to understand them. A student taking on this project would help develop new methods to constrain galaxy evolution via observations of the motions of ionised, atomic and molecular gas. They would apply these methods on state-of-the-art and next-generation large surveys to reveal the gas flows fuelling active galactic nuclei, the masses/concentrations of dark matter halos and/or the properties of the stellar remnants left behind after intense starbursts, depending on their interests. They will have the opportunity to work within several large international collaborations, and obtain data from state-of-the-art telescopes around the world, all while working within the supportive, diverse environment present in the Cardiff Hub for Astrophysics Research and Technology (CHART) at Cardiff University.

解释星系如何形成和演化是天体物理学最大的挑战之一。从隐藏在星系中心的黑洞，到包围它们的暗物质，星系是复杂的。只有利用我们所掌握的一切观测工具，我们才有希望了解它们。一个学生承担这个项目将有助于开发新的方法来约束星系的演化通过观察电离，原子和分子气体的运动。他们将把这些方法应用于最先进的和下一代的大型调查，以揭示为活动星系核提供燃料的气流、暗物质晕的质量/浓度和/或强烈恒星爆发后留下的恒星残骸的性质，这取决于他们的兴趣。他们将有机会在几个大型国际合作中工作，并从世界各地最先进的望远镜中获得数据，同时在卡迪夫大学的卡迪夫天体物理学研究与技术中心（CHART）的支持性，多样化的环境中工作。
