Exploring the physical properties of local and distant galaxies through spectroscopic surveys

这个博士研究项目的目标是探索本地和遥远星系的物理特性（从而探索它们随着宇宙时间的演变），主要通过采用观测方法，特别是通过利用广泛的光谱调查。该项目将包括对光学和近红外光谱数据的分析，在许多情况下，还将提供空间分辨信息（即积分场光谱）。该数据还将与来自成像数据的信息相结合，以获得形态学特性的比较。该项目将限制诸如尘埃和化学富集，ISM激发（包括AGN和激波的存在）等特性的演化，作为全局和已分解星系特性的函数，如恒星形成速率，恒星质量，星系动力学，以及作为红移的函数。观测结果将与理论模型和宇宙学模拟进行比较，以约束驱动星系形成和演化的机制和物理过程。

The goal of this PhD research project is to explore the physical properties of local and distant galaxies (hence exploring their evolution with cosmic time) primarily by adopting an observational approach and, in particular, by exploiting extensive spectroscopic surveys. The project will imply the analysis of both optical and near-IR spectroscopic data that, in many cases, will also provide spatially resolved information (i.e. integral field spectroscopy). This data will also be combined with information from imaging data, to obtain a comparison to morphological properties. The project will constrain the evolution of properties such as dust and chemical enrichment, ISM excitation (including presence of AGN and shocks), as a function of global and resolved galactic properties, such as star formation rate, stellar mass, galaxy dynamics, and as a function of redshift. The observational results will be compared with theoretical models and cosmological simulations to constrain the mechanisms and physical processes driving galaxy formation and evolution.
