The SAMI galaxy survey: exploring the gas-phase mass–metallicity relation
We present a detailed exploration of the stellar mass versus gas-phase metallicity relation (MZR) using integral field spectroscopy data obtained from similar to 1000 galaxies observed by the SAMI galaxy survey. 'These spatially resolved spectroscopic data allow us to determine the metallicity...
