[O iii]/[N ii] as an abundance indicator at high redshift

Open access
Pettini, Max, Pagel, Bernard E. J.·2004·Monthly Notices of the Royal Astronomical Society

Abstract

Among ‘empirical’ methods of estimating oxygen abundances in extragalactic H ii regions, the use of the ratio of nebular lines of [O iii] and [N ii], first introduced by Alloin et al., is reappraised with modern calibration data and shown to have certain advantages over R23≡ ([O ii]+[O iii])/Hβ and N2 ≡[N ii]λ6583/Hα, particularly when applied to star-forming galaxies at high redshifts.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
