We present abundance measurements from 26 emission-line-selected galaxies at z ~ 0.6-0.7. By reaching stellar masses as low as 108 M ☉, these observations provide the first measurement of the intermediate-redshift mass-metallicity (MZ) relation below 109 M ☉. For the portion of our sample above M > 109 M ☉ (8/26 galaxies), we find good agreement with previous measurements of the intermediate-redshift MZ relation. Compared to the local relation, we measure an evolution that corresponds to a 0.12… Expand

We present results from deep Spitzer/Infrared Array Camera (IRAC) observations of 28 metal-poor, strongly star-forming galaxies selected from the DEEP2 Galaxy Survey. By modelling infrared andExpand
Galaxy metallicity scaling relations in the EAGLE simulations
We quantify the correlations between gas-phase and stellar metallicities and global properties of galaxies, such as stellar mass, halo mass, age and gas fraction, in the Evolution and Assembly ofExpand
The Mass–Metallicity Relation at z ∼ 1–2 and Its Dependence on the Star Formation Rate
We present a new measurement of the gas-phase mass–metallicity relation (MZR) and its dependence on star formation rates (SFRs) at 1.3 < z < 2.3. Our sample comprises 1056 galaxies with a meanExpand
Coevolution of metallicity and star formation in galaxies to z ≃ 3.7 - II. A theoretical model
Recent work suggests that galaxy evolution, and the build-up of stellar mass (M-*) over cosmic time, is characterized by changes with redshift of star formation rate (SFR) and oxygen abundance (O/H).Expand

THE MASS-METALLICITY AND FUNDAMENTAL METALLICITY RELATIONS AT z > 2 USING VERY LARGE TELESCOPE* AND SUBARU ** NEAR-INFRARED SPECTROSCOPY OF zCOSMOS GALAXIES
In the local universe, there is good evidence that, at a given stellar mass M, the gas-phase metallicity Z is anti-correlated with the star formation rate (SFR) of the galaxies. It has also beenExpand
