A Rst Step towards a Direct Inversion of the Lyman Forest in Qso Spectra


A method for the recovery of the real space line-of-sight mass density eld from Lyman absorption in QSO spectra is presented. The method makes use of a Lucy-type algorithm for the recovery of the HI density. The matter density is inferred from the HI density assuming that the absorption is due to a photoionized intergalactic medium which traces the mass… (More)
