Povzetek predavanja:
I will discuss the cosmological importance of the matter that is filling the space between galaxies: the Intergalactic Medium (IGM). I will focus on three IGM-related issues: its role as a tracer of the large scale structure; how it can be used to constrain fundamental physical properties (nature of dark matter, variation of fundamental constants and more importantly neutrino masses); its relationship with the galaxy formation process.
The results are based on high and low resolution Lyman-alpha forest quasar spectra (BOSS/SDSS-III and VLT/UVES) and state-of-the-art hydrodynamic simulations.
