Abstract: We present spatially resolved (0.″1) spectra of Hα emission from high-redshift (z ∼ 1.5) star forming galaxies. These observations were obtained at Keck Observatory using the integral field spectrograph OSIRIS and the laser guide star adaptive optics (LGS AO) system. OSIRIS coupled with LGS-AO is able to achieve a full two-dimensional mapping of Hα morphology and dynamics of galaxies at sub-kpc scales. This study is aimed at identifying and analyzing rotationally supported objects in the early universe at a look back time (∼ 9.3 Gyr), close to the estimated age of the Milky Way disk.
