The absorption line spectrum of the QSO J2233-606
P J Outram, B J Boyle, R F Carswell +3
We report on high resolution observations (R=35000) of the Hubble Deep Field South QSO J2233-606 obtained with the University College London Echelle Spectrograph at the AAT. We pre…

A High Deuterium Abundance at z=0.7; Evidence for Cosmic Inhomogeneity?
J. K. Webb, R. F. Carswell, K. M. Lanzetta +3
Recent HST/GHRS observations of the z = 0.7010 absorber toward the QSO 1718+4807 (selected because of apparently ideal characteristics for measuring D/H) yield a D/H significantly…

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…
