As the Universe ages, galaxies find themselves drawn together into filaments, groups and clusters. Galaxies entering these dense environments can experience processes which ultimately lead to a dramatic change in their appearance and internal properties. This project will discover how galaxies are transformed (`quenched') from blue star-forming spiral discs (like our own Milky Way) into passive red elliptical galaxies, through interactions with their environment. This PhD project will be a detailed study of galaxy transformation with environment, comparing those in massive galaxy clusters to the low density "field" environment. You will use spectroscopy and imaging from Hubble Space Telescope, Very Large Telescope, Subaru telescope and the revolutionary Legacy Survey of Space and Time (LSST, https://www.lsst.org/). The results of this project will be physically interpreted through comparison with the outputs from state-of-the-art cosmological simulations of galaxy formation.

随着宇宙年龄的增长，星系发现自己被束缚成细丝，组和簇。进入这些密集环境的星系可以体验过程，最终导致其外观和内部特性发生巨大变化。该项目将通过与环境的互动，发现如何从蓝色星形的螺旋盘（如我们自己的银河系）转变为从蓝色星形螺旋盘（如我们自己的银河系）变成被动红色椭圆星系的星系。该博士学位项目将是对环境的星系转化的详细研究，将大量星系簇的人与低密度“场”环境进行比较。您将使用哈勃太空望远镜，非常大的望远镜，Subaru望远镜和时空的革命遗产调查（LSST，https://wwwww.lsst.org/）的光谱和成像。该项目的结果将通过与银河系形成的最新宇宙学模拟的输出进行物理解释。
