The DEEP Groth Strip Survey XII: The Metallicity of Field Galaxies at 0.26<z<0.82 and the Evolution of the Luminosity-Metallicity Relation
Henry A. Kobulnicky, Christopher N. A. Willmer, Benjamin J. Weiner +6
Using spectroscopic data from the Deep Extragalactic Evolutionary Probe (DEEP) Groth Strip survey (DGSS), we analyze the gas-phase oxygen abundances for 56 emission-line field gala…

Measuring Global Galaxy Metallicities Using Emission Line Equivalent Widths
Chip Kobulnicky, Andrew Phillips
We develop a prescription for estimating the interstellar medium oxygen abundances of distant star-forming galaxies using the ratio EWR_{23} formed from the equivalent widths of th…
