项目摘要

Understanding the nature of the very first galaxies and the physical processes responsible for the build up of their stellar mass and chemical enrichment, as well as their subsequent decline in terms of star formation, are some of the ultimate goals of extragalactic astrophysics. This project will primarily exploit access to two forthcoming, cutting-edge observing facilities, the James Webb Space Telescope and the MOONS spectrograph on the Very Large Telescope, as well as data from the Atacama Large (sub-)Millimetre Array, to achieve an unprecedented leap forward on these topics. The project is divided in two main parts: the first one investigating galaxies in their infancy and their rapid growth and chemical enrichment during the early cosmic epochs; the second part will investigate the competing processes that quench star formation resulting in the emergence of passive systems. Understanding the 'Rise and Fall' of galaxies across the cosmic epochs is a vast area of research. The proposal will focus on the following, ambitious goals: 1) identify and reveal the nature of the first population of galaxies and of their black hole seeds; 2) determine the early evolution of the stellar mass growth and associated chemical enrichment to constrain the primary galaxy evolutionary mechanisms in the early Universe; 3) determine the primary processes responsible for quenching star formation in galaxies across the cosmic epochs.

了解第一个星系的性质以及导致其恒星质量和化学富集的物理过程，以及随后在恒星形成方面的下降，是外层状天体物理学的最终目标。该项目将主要利用对非常大型望远镜的两个即将到来的两个即将到来的，尖端的观测设施，詹姆斯·韦伯太空望远镜和卫星光谱仪，以及来自Atacama大型（亚）毫米阵列的数据，以实现这些主题前进的飞跃。该项目分为两个主要部分：第一个研究星系在其婴儿期和宇宙早期时期的快速生长和化学富集；第二部分将调查导致恒星形成的竞争过程，从而导致被动系统的出现。了解整个宇宙时代的星系的“上升和下降”是广泛的研究领域。该提案将重点介绍以下，雄心勃勃的目标：1）识别并揭示了第一群星系及其黑洞种子的性质； 2）确定恒星质量生长和相关化学富集的早期演变，以限制早期宇宙中主要的星系进化机制； 3）确定导致宇宙时期星系中淬灭星系淬灭星形成的主要过程。
