Abstract

Redshifts and spectrophotometry have been obtained for the high-redshift radio galaxies identified with 3C 6.1, 3C 265, and 3C 352, which have redshifts of z = 0.840, 0.811, and 0.806, respectively. 3C 265 has a very rich strong emission-line spectrum, a nonthermal optical continuum, and a disturbed appearance on deep direct photographs. 3C 6.1 and 3C 352, while also having emission-line spectra, appear to show stellar galaxy continua as well. The rest-frame U - B colors of 3C 6.1 and 3C 352 are bluer than the integrated colors of nearby elliptical galaxies, suggesting color evolution over the 8 billion year look-back time to z = 0.8.
