We perform a kinematic analysis of galaxies at z \sim 2 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 _ { int } ) from 50 - 230 km s ^ { -1 } , consistent with other emission-line studies of z \sim 2 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 \sim 2 .
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 \sim 2 are not significantly different between the cluster and field environments .
