The warm and hot gas between galaxies and within their halo is a reservoir of matter from which proto-galaxies can form. MOSAIC will provide an unprecedented map of the distant 3D structures of this gas as well as evaluating for the first time the distribution of the different baryonic components of the matter. | ||
Detailed simulations show that MOSAIC will play an important role in the mapping of the intergalactic medium. An ambitious galaxy survey with MOSAIC will provide a 3D map of the IGM at z > 3, complementing similar surveys that will focus on lower redshifts. In synergy with the missions like Euclid and JWST, MOSAIC will enable us to probe the full redshift evolution of galaxy growth in the cosmic web throughout the cosmic period of intense star formation.
