Astronomy & Astrophysics Seminar: Kinematics of star-forming galaxies at z~1-2 with KMOS^3D

Abstract: 

Time-intensive observations of large samples of galaxies during the peak epoch of cosmic star-formation rate density have become possible with multiplexing instruments such as KMOS/VLT. Our KMOS^3D survey targeting ionized gas emission at 0.6<z<2.7 provides spatially resolved information on the ISM conditions and kinematics of more than 600 galaxies. A prominent result of this survey is that the majority of massive, star-forming galaxies at this epoch is dominated by ordered disk rotation, with an increasing contribution from turbulent motions at higher redshifts. I will present recent results from the KMOS^3D survey on the kinematics of massive main-sequence galaxies. In particular, I will show how high-z rotation curve measurements can be utilized to constrain the dynamical support of these galaxies, and how this advances our understanding of galaxy evolution.
