3C 234; z=0.184

3C 234 exhibits a bright quasar-like nucleus in the NICMOS image, and is known to be a broad-line radio galaxy [McCarthy et al.1995] with classical double FR II radio source. In the optical [de Koff et al.1996,McLure et al.1999] there are features emanating from the nucleus in the east and west direction. The western feature, described as a tidal arm by McLure et al. is detectable on the new NICMOS image. There are two additional sources to the west in the same direction, the furthest of which is also detectable in F555W, and F702W. Both are detectable in F675W. This galaxy is known to have strong extended emission lines which likely explain these features. Pa  (1.28 m) is in the passband of F160W at the redshift of 3C 234.
