THE KMOS 3D SURVEY: DESIGN, FIRST RESULTS, AND THE EVOLUTION OF GALAXY KINEMATICS FROM 0.7 ⩽ z ⩽ 2.7

We present the KMOS 3D survey, a new integral field survey of over 600 galaxies at 0.7 1, implying that the star-forming 'main sequence' (MS) is primarily composed of rotating galaxies at both redshift regimes. When considering additional stricter criteria, the H kinematic maps indicate at least 70% of the resolved galaxies are disk-like systems. Our high-quality KMOS data confirm the elevated velocity dispersions reported in previous IFS studies at z 0.7. For rotation-dominated disks, the average intrinsic velocity dispersion decreases by a factor of two from 50 km s -1 at z 2.3 to 25 km s -1 at z 0.9. Combined with existing results spanning z 0 -3, we show that disk velocity dispersions follow an evolution…
