A robust deuterium abundance; Re-measurement of the z=3.256 absorption system towards the quasar PKS1937-1009
S. Riemer-Sørensen, J. K. Webb, N. Crighton +6
The primordial deuterium abundance is an important tracer of the fundamental physics taking place during Big Bang Nucleosynthesis. It can be determined from absorption features alo…
