Deuterium to hydrogen towards QSO 1009+2956 from a mesoturbulent model
Sergei A. Levshakov, David Tytler, Scott Burles
We present a new analysis of the deuterium absorption at z = 2.504 towards the quasar Q1009+2956 using the mesoturbulent model which accounts for possible correlations in the large…

A uniform primordial deuterium abundance stemmed from QSO observations
Sergei A. Levshakov
The discordance between `low' and `high' primordial D/H measurements can be considerably reduced if the analysis of the H+D profiles accounts for the correlated velocity field of b…

The D/H ratio at z=0.7 toward Q 1718+4807
Sergei A. Levshakov, Wilhelm H. Kegel, Fumio Takahara
The apparent discrepancy between low and high D abundances derived from QSO spectra may be caused by spatial correlations in the stochastic velocity field. If one accounts for such…
