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…

HD Molecular Lines in an Absorption System at Redshift z = 2.3377
D. Varshalovich, A. Ivanchik, P. Petitjean +2
We have analyzed the spectrum of the quasar PKS 1232+082 obtained by Petitjean et al. (2000). HD molecular lines are identified in an absorption system at the redshift z=2.3377. Th…

A near-solar metallicity damped Lyman-alpha system toward the BAL quasar Tol 1037-2703
R. Srianand, P. Petitjean
We report the detection of a Broad Absorption Line (BAL) outflow in the spectrum of Tol 1037-2703 with three main BALs at 36000, 25300 and 22300~\kms outflow velocities. Although t…
