Coincidences of high density peaks in UVES spectra of QSO pairs
Valentina D'Odorico, Patrick Petitjean, Stefano Cristiani
We present preliminary results of an investigation of the clustering properties of high matter density peaks between redshift ~2 and ~3, as traced by Lyman limit and Damped Ly-alph…
H_2 molecules in damped systems
R. Srianand, P. Petitjean, C. Ledoux
Damped Lyman alpha systems seen in the spectra of high-z QSOs arise in high-density neutral gas in which molecular hydrogen (H_2) should be conspicuous. Systematic searches to dete…
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…
