The Intergalactic medium (IGM) is an extraordinary repository of information about cosmic evolution and, more in particular, about the interplay between IGM and galaxies or quasars. In fact, the IGM keeps the imprints of large scale structure evolution, reionization, thermal and metallicity history as well as of all those feedback effects that shape the formation and evolution of structures. For this reason, the study of the properties of quasars' and galaxies' environment can provide a wealth of information on e.g. their emitting spectra, intrinsic luminosities, lifetimes and star formation activity.Thus, the study of the IGM is fundamental for a better understanding of the galaxy/quasar formation and evolution process as a whole.The main aim of the project presented in this proposal is to improve our current knowledge of the IGM physical state at different epochs, both during and after the reionization process.

星系际介质（IGM）是宇宙演化信息的非凡宝库，特别是关于IGM与星系或类星体之间的相互作用。事实上，IGM保留了大尺度结构演化、再电离、热和金属丰度历史以及所有那些塑造结构形成和演化的反馈效应的印记。因此，对类星体和星系环境性质的研究可以提供丰富的信息，例如它们的发射光谱、本征光度、寿命和星星形成活动。IGM的研究是更好地了解银河系的基础。类星体的形成和演化过程作为一个整体。在这个建议中提出的项目的主要目的是提高我们目前的知识IGM物理状态在不同的时期，无论是在再电离过程中和之后。
