Measuring the Physical Conditions in High-Redshift Star-Forming Galaxies: Insights from KBSS-MOSFIRE
Allison L. Strom, Charles C. Steidel, Gwen C. Rudie +2
We use photoionization models designed to reconcile the joint rest-UV-optical spectra of high-z star-forming galaxies to self-consistently infer the gas chemistry and nebular ioniz…
Observational signatures of a warped disk associated with cold-flow accretion
Hadi Rahmani, Céline Péroux, Ramona Augustin +9
We present MUSE observations of the field of the quasar Q0152020 whose spectrum shows a Lyman limit system (LLS) at redshift , with a metallicity Z $\gtrsim…
One percent determination of the primordial deuterium abundance
Ryan Cooke, Max Pettini, Charles C. Steidel
We report a reanalysis of a near-pristine absorption system, located at a redshift z_abs=2.52564 toward the quasar Q1243+307, based on the combination of archival and new data obta…
Zinc in the Sculptor dwarf spheroidal galaxy
Ása Skúladóttir, Eline Tolstoy, Stefania Salvadori +2
From ESO VLT/FLAMES/GIRAFFE spectra, abundance measurements of Zn have been made in 100 individual red giant branch (RGB) stars in the Sculptor dwarf spheroidal galaxy. Th…
The comoving mass density of MgII from to
Alex Codoreanu, Emma V. Ryan-Weber, Neil H. M. Crighton +4
We present the results of a survey for intervening MgII absorbers in the redshift range z 2-6 in the foreground of four high redshift quasar spectra, 5.796.1…
Discovery of the most metal-poor damped Lyman-alpha system
Ryan Cooke, Max Pettini, Charles C. Steidel
We report the discovery and analysis of the most metal-poor damped Lyman-alpha (DLA) system currently known, based on observations made with the Keck HIRES spectrograph. The metal…
