We review the use of emission lines for understanding galaxy evolution, focusing on
excitation source, metallicity, ionization parameter, ISM pressure, and electron density. We …

Abstract We utilize Sloan Digital Sky Survey imaging and spectroscopy of~ 53,000 star-
forming galaxies at z~ 0.1 to study the relation between stellar mass and gas-phase …

We investigate the effect of metallicity calibrations, AGN classification, and aperture covering
fraction on the local mass-metallicity (MZ) relation using 27,730 star-forming galaxies from …

Simple relations for deriving the oxygen abundance in H ii regions with intensities of the
three strong emission lines R 2, R 3, and N 2 (R calibration) or S 2, R 3, and N 2 (S …

We have used a combination of stellar population synthesis and photoionization models to
develop a set of ionization parameter and abundance diagnostics based only on the use of …

We investigate the relationships between the characteristic oxygen abundance, the radial
abundance gradient, and the macroscopic properties of spiral galaxies by examining the …

We present intermediate-resolution optical spectrophotometry of 65 galaxies obtained in
support of the Spitzer Infrared Nearby Galaxies Survey (SINGS). For each galaxy we obtain …

H II region abundances - Model oxygen line ratios ADS Classic is now deprecated. It will be
completely retired in October 2019. This page will automatically redirect to the new ADS …

We measure nebular oxygen abundances for 204 emission-line galaxies with redshifts 0.3<
z< 1.0 in the Great Observatories Origins Deep Survey-North (GOODS-N) field using spectra …

Recently, Nicholls et al., inspired by in situ observations of solar system astrophysical
plasmas, suggested that the electrons in H ii regions are characterized by a κ-distribution of …
