TLDR
In this paper, 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 Ρ 23 ≡ ([On] + [OIII])/Hβ and N2 ≡ [N 2] λ6583/Hα, particularly when applied to star-forming galaxies at high redshifts.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 Ρ 23 ≡ ([On] + [O III])/Hβ and N2 ≡ [N II] λ6583/Hα, particularly when applied to star-forming galaxies at high redshifts.read more

The host galaxies and classification of active galactic nuclei
TL;DR: In this paper, the authors present an analysis of the host properties of 85224 emission-line galaxies selected from the Sloan Digital Sky Survey and derive a new empirical classification scheme which cleanly separates star-forming galaxies, composite AGN-H ii galaxies, Seyferts and LINERs and study the host galaxy properties of these different classes of objects.

Classification parameters for the emission-line spectra of extragalactic objects
TL;DR: In this paper, the merits of various emission-line intensity ratios for classifying the spectra of extragalactic objects were investigated and it was shown empirically that several combinations of easily-measured lines can be used to separate objects into one of four categories according to the principal excitation mechanism: normal H II regions, planetary nebulae, objects photoionized by a power-law continuum, and objects excited by shock-wave heating.
