The Deuterium Abundance Towards Q1937-1009
Scott Burles, David Tytler
We present a new measurement of the deuterium-to-hydrogen ratio (D/H) in the Lyman limit absorption system at towards Q1937--1009. We use an improved method to measure…

The Deuterium Abundance Towards Q1009+2956
Scott Burles, David Tytler
We present a measurement of the deuterium to hydrogen ratio (D/H) in a metal-poor absorption system at redshift towards the QSO 1009+2956. We apply the new method of Burl…

Upper Limits on Metals in Quasar Lyman-Alpha Forest Clouds: Absence of C IV Lines in Echelle Spectra
D. Tytler, X. -M. Fan
Recently Lu presented tentative evidence for C IV lines in QSO Lyman-alpha forest systems with strong lines. We have performed a similar search for C IV in our 10 km/sec echelle sp…
