The Structure of High Redshift Galactic Halos
Sara L. Ellison, Rodrigo Ibata, Max Pettini +4
Observations of multiple or lensed QSOs at high redshift can be used to probe transverse structure in intervening absorption systems. Here we present results obtained from STIS spe…

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…

Structure of the MgII and damped Lyman-alpha systems along the line of sight to APM 08279+5255
Patrick Petitjean, Bastien Aracil, R. Srianand +1
A study of the absorption systems toward the gravitationally lensed quasar APM 08279+5255 is presented. Most of the MgII systems in the redshift range 1.2-2.07, although saturated,…
