Precision measures of the primordial abundance of deuterium

Ryan Cooke, +4 more
- 14 Aug 2013 - 
TL;DR: In this paper, the primordial abundance of deuterium has been measured in the very metal-poor (Fe/H] = -2.06726 toward the QSO SDSS J1358+6522.
Journal ArticleDOI

A carbon-enhanced metal-poor damped Lyα system: probing gas from Population III nucleosynthesis?

Ryan Cooke, +4 more
- 22 Dec 2010 - 
TL;DR: In this paper, high-resolution observations of an extremely metal-poor damped Lyα system (DLA) at z((abs) = 2.340 0972 in the spectrum of the QSO J0035−0918, exhibiting an abundance pattern consistent with model predictions for the supernova yields of Population III stars.

THE MOST METAL-POOR DAMPED Lyα SYSTEMS: AN INSIGHT INTO DWARF GALAXIES AT HIGH-REDSHIFT

Ryan Cooke, +2 more
- 10 Feb 2015 - 
TL;DR: In this paper, the kinematics, chemistry, and physical properties of a sample of the most metal-poor damped Ly? systems (DLAs) were analyzed to uncover their links to modern-day galaxies.
Journal ArticleDOI

Ryan Chornock, +24 more
- 20 Sep 2011 -
