Scientific paper

We propose to use the high-resolution infrared imaging capabilities of NICMOS to image three powerful, z>2 radio galaxies in the light of redshifted OIII and HAlpha+NII to map their bright, optical emission--line morphologies on scales as small as 1-2 kpc. We will compare the sizes and detailed structures of the nebulae to the radio and visual continuum morphologies on sub-galactic size scales, and relate them to those found in lower redshift radio galaxies studied with HST and ground-based observatories over the same wavelength region. By combining these data with spatially resolved near infrared spectra of these objects obtained with the W.M. Keck and Hale 200 inch Telescopes, we will explore the relationship between the morphology, the excitation, and the dynamics of the optical emission--line nebulae for the first time in radio galaxies at redshifts of z>2.
