ULTRA-STEEP-SPECTRUM RADIO-SOURCES .1. 4C OBJECTS

We present radio total intensity and polarization images and complete optical identifications of a representative sample of ultra-steep-spec trum 4C objects. The radio morphologies are all resolved into double l obes or triples with cores. The radio polarization intensity morpholog ies are strikingly asymmetric. The optical identifications consist of galaxies in distant clusters (0.4 < z < 1.0), quasars, and high-redshi ft (z > 1) radio galaxies. We identify several (1 < z < 2) cluster can didates, and faint candidates for very high redshift radio galaxies.
