University of Sussex Astronomy Consolidated Grant 2023-2026

这项提议寻求支持，通过解决我们这个时代一些最紧迫的天体物理问题，继续进行河外天体物理和宇宙学的广泛研究计划，例如：-在早期宇宙中运行的物理定律是什么？-宇宙的初始结构是如何形成的？-宇宙是如何演变的，暗物质和暗能量扮演着什么角色？-第一批恒星、黑洞和星系是什么时候和如何诞生的？-恒星和星系是如何进化的？为了实现这些目标，我们将结合尖端观测、数值模拟和统计技术。这项建议由10个不同但相互关联的项目组成，每个项目都涉及一名或多名教职员工和研究人员，可归纳为三大主题：早期和晚期宇宙宇宙学；银河系模拟和建模；星系和星系团观测和分析：早期和晚期宇宙宇宙学：一系列项目将涉及对膨胀、暗能量和大尺度结构的理论预测和观测限制。我们的工作包括发展理论框架和分析尖端观测数据集。星系模拟和建模：我们将利用Peta尺度的计算设施对第一批结构的形成和演化进行详细研究，并做出统计预测，这些预测可用于开发现有和即将使用的观测设施，如詹姆斯·韦伯空间望远镜、欧几里得、LOFAR和平方公里阵列。星系和星系团观测：我们将利用多波长观测来回答有关星系形成和演化的各种问题。我们将继续利用我们参与的暗能量调查、欧几里德、詹姆斯·韦伯太空望远镜、Vista上的4M多目标光谱望远镜(4MOST)、LOFAR、维拉·鲁宾天文台和XMM-牛顿星系团调查。我们还请求为项目10所附的一个外联项目提供支助。

This proposal seeks support to continue an extensive programme of research into extragalactic astrophysics and cosmology, by addressing some of the most pressing astrophysical questions of our time, such as:- What are the laws of physics operating in the early Universe?- How did the initial structure in the universe form?- How is the universe evolving and what roles do dark matter and dark energy play?- When and how were the first stars, black holes and galaxies born?- How do stars and galaxies evolve?To achieve these aims we will combine cutting-edge observations, numerical simulations, and statistical techniques. This proposal consists of 10 varied but interconnected projects, each involving one or more faculty members and researchers, that can be collected into three broad themes: Early and late universe cosmology; Galaxy simulation and modelling; Galaxy and cluster observations and analysis:Early and late universe cosmology: a series of projects will address theoretical predictions and observational constraints on inflation, dark energy and large scale structure. Our work encompasses both the development of theoretical frameworks and the analysis of cutting edge observational data-sets.Galaxy simulation and modelling: we will use Peta-scale computing facilities to carry out detailed studies of the formation and evolution of the first structures, and make statistical predictions that can be used in the exploitation of current and upcoming observational facilities such as James Webb Space Telescope, Euclid, LOFAR, and the Square Kilometre Array.Galaxy and cluster observations: we will make use of multi-wavelength observations to answer a variety of questions concerning the formation and evolution of galaxies. We will continue to exploit our involvement in the Dark Energy Survey, Euclid, the James Webb Space Telescope, the 4m Multi-Object Spectroscopic Telescope (4MOST) on VISTA, LOFAR, the Vera Rubin Observatory, and the XMM-Newton Cluster Survey. We also request support for an outreach project attached to Project 10.
