Stellar Mass--Gas-phase Metallicity Relation at $0.5\le z\le 0.7$: A Power Law with Increasing Scatter toward the Low-mass Regime

Abstract

We present the stellar mass ($M_{\ast }$)--gas-phase metallicity relation (MZR) and its scatter at intermediate redshifts ($0.5\le z\le 0.7$) for 1381 field galaxies collected from deep spectroscopic surveys. The star formation rate (SFR) and color at a given $M_{\ast }$ of this magnitude-limited ($R\lesssim 24$ AB) sample are representative of normal star-forming galaxies. For masses below $10^9{M}_{\odot }$, our sample of 237 galaxies is $\sim$10 times larger than those in previous studies beyond the local universe. This huge gain in sample size enables superior constraints on the MZR and its scatter in the low-mass regime. We find a power-law MZR at $10^8{M}_{\odot }<M_{\ast }<10^{11}{M}_{\odot }$: $12+log(O/H)=(5.83\pm 0.19)+(0.30\pm 0.02)log(M_{\ast }/M_{\odot })$. Our MZR shows good agreement with others measured at similar redshifts in the literature in the intermediate and massive regimes, but is shallower than the extrapolation of the MZRs of others to masses below $10^9{M}_{\odot }$. The SFR dependence of the MZR in our sample is weaker than that found for local galaxies (known as the Fundamental Metallicity Relation). Compared to a variety of theoretical models, the slope of our MZR for low-mass galaxies agrees well with predictions incorporating supernova energy-driven winds. Being robust against currently uncertain metallicity calibrations, the scatter of the MZR serves as a powerful diagnostic of the stochastic history of gas accretion, gas recycling, and star formation of low-mass galaxies. Our major result is that the scatter of our MZR increases as $M_{\ast }$ decreases. Our result implies that either the scatter of the baryonic accretion rate or the scatter of the $M_{\ast }$--$M_{halo}$ relation increases as $M_{\ast }$ decreases. Moreover, our measures of scatter at $z=0.7$ appears consistent with that found for local galaxies.
