The primordial deuterium abundance of the most metal-poor damped Lyman-alpha system
Ryan Cooke, Max Pettini, Kenneth M. Nollett +1
We report the discovery and analysis of the most metal-poor damped Lyman-alpha (DLA) system currently known, which also displays the Lyman series absorption lines of neutral deuter…
Spatially Resolved Emission of a High Redshift DLA Galaxy with the Keck/OSIRIS IFU
Regina A. Jorgenson, Arthur M. Wolfe
We present the first Keck/OSIRIS infrared IFU observations of a high redshift damped Lyman-alpha (DLA) galaxy detected in the line of sight to a background quasar. By utilizing the…
Precision measures of the primordial abundance of deuterium
Ryan Cooke, Max Pettini, Regina A. Jorgenson +2
We report the discovery of deuterium absorption in the very metal-poor ([Fe/H] = -2.88) damped Lyman-alpha system at z_abs = 3.06726 toward the QSO SDSS J1358+6522. On the basis of…
The Magellan Uniform Survey of Damped Lyman alpha Systems I: Cosmic Metallicity Evolution
Regina A. Jorgenson, Michael T. Murphy, Rodger Thompson
We present the chemical abundance measurements of the first large, medium-resolution, uniformly selected damped Lyman alpha system (DLA) survey. The sample contains 99 DLAs towards…
The explosion energy of early stellar populations: The Fe-peak element ratios in low metallicity damped Lyman-alpha systems
Ryan Cooke, Max Pettini, Regina A. Jorgenson +3
The relative abundances of the Fe-peak elements (Ti-Zn) at the lowest metallicities are intimately linked to the physics of core-collapse supernova explosions. With a sample of 25…
Spectral Polarization of the Redshifted 21 cm Absorption Line Toward 3C 286
Arthur M. Wolfe, Regina A. Jorgenson, Timothy Robishaw +2
A re-analysis of the Stokes-parameter spectra obtained of the z=0.692 21 cm absorption line toward 3C 286 shows that our original claimed detection of Zeeman splitting by a line-of…
