On the kinematics of damped Lyman-alpha systems
C. Ledoux, P. Petitjean, J. Bergeron +2
We report on high spectral resolution observations of five damped Ly-alpha absorbers. Line velocity profiles and heavy element abundances are discussed. Nitrogen is found to have a…

High Resolution Observations of the QSO BR1202-0725: Deuterium and Ionic Abundances at Redshifts Above z=4
E. J. Wampler, G. M. Williger, J. A. Baldwin +3
We present results from 12 km/s resolution echelle spectroscopy of the bright QSO BR1202-0725. A preliminary analysis shows that high metallicity narrow line absorption c…
