[80.10] Spatial v. Rotation Curve Morphlogies for 1 < z < 1.4 Disk Galaxies

S. A. Kassin (UCO/Lick, UC Santa Cruz)

We correlate optical morphologies of galaxies from 1 < z < 1.4 in the Extended Groth Strip with the deviations from symmetry in their rotation curves. Optical morphologies are given by Gini/M20 results for ACS imaging. Rotation curves derived from the [OII] line in DEEP2 spectra are modeled with an arctan function and analyzed on a galaxy-by-galaxy basis to detect any deviations from symmetry. Well-ordered disks are found to exist from 1 < z < 1.4. From a preliminary visual inspection of the data, not all optically well-ordered galaxies have a well-ordered rotation curve, and vice-versa. It also appears to be the case that not all galaxies with irregular morphologies have asymmetric rotation curves, and vice-versa.
