The metallicities of low stellar mass galaxies and the scatter in the mass-metallicity relation

Zahid, H J; Bresolin, Fabio; Kewley, Lisa; Coil, Alison L; Dave, R

Description

In this investigation, we quantify the metallicities of low-mass galaxies by constructing the most comprehensive census to date. We use galaxies from the Sloan Digital Sky Survey (SDSS) and DEEP2 survey and estimate metallicities from their optical emission lines. We also use two smaller samples from the literature that have metallicities determined by the direct method using the temperature sensitive [O III]λ4363 line. We examine the scatter in the local mass-metallicity (MZ) relation...[Show more]
