Title: Resolving the kinematics of high-redshift galaxy assembly

Abstract: We propose to solve a major debate on-going in the high-redshift literature: what is the dominant kinematic mode of high-redshift star-formation and galaxy assembly? Two previous kinematic surveys with Integral Field Spectrographs have reached different fundamental conclusions, with one suggesting that star formation occurs in rapidly rotating turbulent disks, and the other that star formation occurs in 'dispersion dominated systems' with little to no systemic rotation about a preferred kinematic axis. While some difference may genuinely arise across the galaxy population, systematic instrumental limitations of the two surveys may also significantly bias their respective results. The demonstrated greater sensitivity of NIFS and deep definitive exposures will allow us test these scenarios for 8 key objects.
