The correlation of the Lyman-alpha forest and metals in close pairs of hight-redshift quasars
F. Coppolani, P. Petitjean, F. Stoehr +6
We derive the transverse flux correlation function in the Lyman-alpha forest at z~2.1 from VLT-FORS observations of a total of 32 pairs of quasars. The shape and correlation length…

3D Spatial Distribution of the Intergalactic Medium
Patrick Petitjean, Emmanuel Rollinde, Bastien Aracil +2
Very recently a new inversion method has been developped to analyze the intergalactic medium seen in absorption in quasar spectra (the so-called Lyman-alpha forest). This method is…
