Metallicities, dust and molecular content of a QSO-Damped Lyman-α system reaching log N (H i) = 22: An analog to GRB-DLAs
R. Guimarães, P. Noterdaeme, P. Petitjean +4
We present the elemental abundance and H2 content measurements of a Damped Lyman-α (DLA) system with an extremely large H i column density, log N(H i) (cm-2) = 22.0+/-0.10, at zabs…

High-ion absorption in the proximate damped Lyman-alpha system toward Q0841+129
Andrew J. Fox, Cédric Ledoux, Patrick Petitjean +2
We present VLT/UVES spectroscopy of the quasar Q0841+129, whose spectrum shows a proximate damped Lyman-alpha (PDLA) absorber at z=2.47621 and a proximate sub-DLA at z=2.50620, bot…
