Kinemetry of High-Redshift Galaxies

Explore the kinematics of high-redshift galaxies to differentiate between rotating disks and major mergers using SINS survey data. Analyze velocity fields and classify z~0 and z~2 template galaxies. Study the formation and evolution of disks at z~2, noting the role of rapid inflow scenarios and secular evolution.
