The spatial distribution of the gas in the intergalactic medium and its physical properties can be recovered thanks to the characteristics of the Ly$\alpha$ absorption lines that are observed in the spectra of high redshift quasars, the so-called Ly$\alpha$ forest. We use inversion methods applied to a network of lines of sight to infer the topology of the intergalactic medium, based on reconstruction of the density field. The method has already been tested on simulated data.
