Abstract

The gas metallicity of galaxies is often estimated using strong emission lines such as the optical lines of [O III] and [O II]. The most common measure is "R23," defined as ([O II]lambda lambda 3726, 3729 + [O III]lambda lambda 4959,5007)/H beta. Most calibrations for these strong-line metallicity indicators are for continuum selected galaxies. We report a new empirical calibration of R23 for extreme emission-line galaxies using a large sample of about 800 star-forming green pea galaxies with reliable T-e-based gas-phase metallicity measurements. This sample is assembled from Sloan Digital Sky Survey (SDSS) Data Release 13 with the equivalent width of the line [O III]lambda 5007 > 300 angstrom or the equivalent width of the line H beta > 100 angstrom in the redshift range 0.011 < z < 0.411. For galaxies with strong emission lines and large ionization parameter (which manifests as log [O III]lambda lambda 4959,5007/[O II]lambda lambda 3726,3729 >= 0.6), R23 monotonically increases with log(O/H) and the double-value degeneracy is broken. Our calibration provides metallicity estimates that are accurate to within similar to 0.14 dex in this regime. Many previous R23 calibrations are found to have bias and large scatter for extreme emission-line galaxies. We give formulae and plots to directly convert R23 and [O III]lambda lambda 4959,5007/[O II]lambda lambda 3726,3729 to log(O/H). Since green peas are best nearby analogs of high-redshift Ly alpha emitting galaxies, the new calibration offers a good way to estimate the metallicities of both extreme emission-line galaxies and high-redshift Ly alpha emitting galaxies. We also report on 15 galaxies with metallicities less than 1/12 solar, with the lowest metallicities being 12+ log(O/H) = 7.25 and 7.26.
