Statistical Measurement of Primordial Deuterium Abundance
Martin H. Rugers, Craig J. Hogan
Lyman series absorption features and corresponding metal lines in three high-resolution quasar spectra are fitted in the standard way with thermally broadened discrete redshift com…

High Deuterium Abundance in a New Quasar Absorber
Martin Rugers, Craig J. Hogan
We present a new analysis of an absorption system in the spectrum of Q0014+813, with particular attention to a single cold cloud at redshift . Features are identified a…

Confirmation of high deuterium abundance in QSO absorbers
M. Rugers, C. J. Hogan
We present a new analysis of a Keck spectrum of Q0014+813, with a new model of the absorbing cloud. We fit Lyman series absorption of the dominant HI components, including…
