INFRARED IMAGES OF DISTANT 3C RADIO GALAXIES

We have obtained J (1.2 μm) and K (2.2 μm) images of eight 3CR radio galaxies with redshifts from 0.7 to 1.8. Most of the objects were known to have extended asymmetric optical continuum or line emission aligned with the radio lobe axis. In general, we find that the infrared morphologies of these galaxies are just as peculiar as their optical morphologies. For all the galaxies, when asymmetric structure is present in the optical, structure with the same orientation is seen in the infrared and must be accounted for in any model to explain the alignment of optical and radio emission.
