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.

该博士研究项目的目的是探索主要通过观察方法，尤其是通过利用广泛的光谱调查来探索局部和遥远星系的物理特性（因此，使用宇宙时间探索其进化）。该项目将暗示对光学和近红外光谱数据的分析，在许多情况下，这些数据还将提供空间分辨的信息（即积分磁场光谱）。该数据还将与来自成像数据的信息相结合，以获得与形态学特性的比较。该项目将限制诸如粉尘和化学富集，ISM激发（包括存在AGN和冲击）之类的特性的演变，这是全球和分辨出的银河系特性的函数，例如恒星形成速率，出色的质量，星系动力学，以及红色速度的函数。观察结果将与理论模型和宇宙学模拟进行比较，以限制驱动星系形成和进化的机制和物理过程。
