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.
