Kinematics of z~1–2 star-forming galaxies with KMOS^3D: intrinsic
velocity dispersion

Abstract: Kinematics are a powerful tool to study galaxy evolution
because they are directly affected by transformative processes such as
accretion, gravitational instabilities, feedback, or outflows. The
incidence or strength of several of these processes changes with cosmic
time, allowing us to connect certain kinematic signatures with specific
physical processes. I will present recent results on the kinematics of
star-forming galaxies during the peak epoch of cosmic star formation
from the KMOS^3D survey, with a focus on the redshift evolution of the
intrinsic velocity dispersion. Combining observational evidence and
theoretical predictions, I will discuss the origin of the elevated
velocity dispersions at high redshift.
