Abstract (from CDS):
We present the completed KMOS
3D survey, an integral field spectroscopic survey of 739 log(M
*/M
☉)> 9 galaxies at 0.6 < z < 2.7 using the K-band Multi Object Spectrograph (KMOS) at the Very Large Telescope. The KMOS
3D survey provides a population-wide census of kinematics, star formation, outflows, and nebular gas conditions both on and off the star-forming galaxy main sequence through the spatially resolved and integrated properties of Hα, [N II], and [S II] emission lines. We detect Hα emission for 91% of galaxies on the main sequence of star formation and 79% overall. The depth of the survey has allowed us to detect galaxies with star formation rates below 1 M
☉ yr
–1, as well as to resolve 81% of detected galaxies with >=3 resolution elements along the kinematic major axis. The detection fraction of Hα is a strong function of both color and offset from the main sequence, with the detected and nondetected samples exhibiting different spectral energy distribution shapes. Comparison of Hα and UV+IR star formation rates reveal that dust attenuation corrections may be underestimated by 0.5 dex at the highest masses (log(M
*/M
☉)> 10.5). We confirm our first year results of a high rotation-dominated fraction (monotonic velocity gradient and v
rot/σ
0> sqrt(3.36)) of 77% for the full KMOS
3D sample. The rotation-dominated fraction is a function of both stellar mass and redshift, with the strongest evolution measured over the redshift range of the survey for galaxies with log(M
*/M
☉)< 10.5. With this paper, we include a final data release of all 739 observed objects (
