ZFIRE: The Kinematics of Star-Forming Galaxies as a Function of
  Environment at z~2
  We perform a kinematic analysis of galaxies at $z\sim2$ in the COSMOS legacy
field using near-infrared (NIR) spectroscopy from Keck/MOSFIRE as part of the
ZFIRE survey. Our sample consists of 75 Ks-band selected star-forming galaxies
from the ZFOURGE survey with stellar masses ranging from
log(M$_{\star}$/M$_{\odot}$)$=9.0-11.0$, 28 of which are members of a known
overdensity at $z=2.095$. We measure H$\alpha$ emission-line integrated
velocity dispersions ($\sigma_{\rm int}$) from 50$-$230 km s$^{-1}$, consistent
with other emission-line studies of $z\sim2$ field galaxies. From these data we
estimate virial, stellar, and gas masses and derive correlations between these
properties for cluster and field galaxies at $z\sim2$. We find evidence that
baryons dominate within the central effective radius. However, we find no
statistically significant differences between the cluster and the field, and
conclude that the kinematics of star-forming galaxies at $z\sim2$ are not
significantly different between the cluster and field environments.
