N2 - The KMOS3D survey will provide near-IR IFU observations of a mass-selected sample of ∼600 star-forming galaxies at 0 .7 < z < 2 . 7 with the K-band Multi Object Spectrograph (KMOS) at the VLT.We present kinematic results for a first sample of ∼200 galaxies, focusing on the evolution of the gas velocity dispersion with redshift. Combined with existing measurements, we find an approximate (1+ z ) evolution from z ∼ 4 to the present day, which can be understood from the co-evolution of the gas fraction and specific star formation rate (sSFR) in the the equilibrium picture of galaxy evolution. We combine the KMOS3D sample with data from the LUCI and SINFONI spectrographs, as well as multi-wavelength HST imaging from CANDELS, to address the relations between stellar mass, SFR, and the [N II]/H α flux ratio as an indicator of gas-phase metallicity for a sample of 222 star-forming galaxies. We find a constant slope at the low-mass end of the mass-metallicity relation and can fully describe its redshift evolution through the evolution of the characteristic turnover mass where the relation begins to flatten at the asymptotic metallicity. At a fixed mass and redshift, our data do not show a correlation between the [N II]/H α ratio and SFR.
