We present high resolution, emission line-free near-infrared images of 11 powerful radio galaxies at redshifts 0.7 < z < 1.8 observed with NICMOS Camera 2 on HST. The high angular resolution afforded by HST permits a detailed study of galaxy morphology in these systems. WFPC2 images of these galaxies sample the rest-frame UV emission, which is often dominated by scattered light and other AGN-related processes. The extended UV continuum is typically aligned with the major axis of the radio source and in all objects shows a peculiar morphology dominated by small clumps or filaments. The NICMOS images sample the rest-frame optical emission, which is largely dominated by starlight. In contrast to their rest-frame UV morphologies, the optical / near-infrared morphologies of these systems are more symmetric and are consistent with dynamically relaxed elliptical host galaxies. The active nucleus does not appear to contribute significantly to the near-infrared light. Our observations are consistent with the hypothesis that the host galaxies of z~ 1-2 radio galaxies are similar to modern-day gE galaxies.
