On Measuring Nebular Chemical Abundances in Distant Galaxies Using Global Emission‐Line Spectra

Abstract: The advent of 8-10 meter class telescopes enables direct measurement of the chemical properties in the ionized gas of cosmologically-distant galaxies with the same nebular analysis techniques used in local H II regions. We show that spatially unresolved (i.e., global) emission line spectra can reliably indicate the chemical properties of distant star-forming galaxies. However, standard nebular chemical abundance measurement methods (those with a measured electron temperature from [O III] λ4363) may be subject … Show more

“…The grids of photoionization models are often used to establish the relation between strong oxygen line intensities and oxygen abundances (Edmunds & Pagel 1984;McCall et al 1985;Dopita & Evans 1986;Kobulnicky et al 1999;Kewley & Dopita 2002, among others). The relation (between strong oxygen line intensities and oxygen abundances) established on the basis of the grids of the photoionization models for H  regions will be referred to as theoretical or model calibration.…”
