The Rest-Frame Optical Properties of Star-Forming Galaxies at z~2

Abstract

We present preliminary results from Hα spectroscopy and deep K-band imaging of UV-selected star-forming galaxies at z~2. We see evidence for relatively mature, massive galaxies in the form of an increase in the mean velocity dispersion and the mean ${\cal R} - K_s$ color from z~3 to z~2, and in the approximately solar metallicities of a significant number of the z~2 galaxies. There appears to be substantial diversity in the z~2 sample, as other kinematic measurements suggest that some of the galaxies are still in the process of formation.
