Identifications and redshifts of faint 3CR radio sources

We report new and confirmed optical identifications of 12 3CR radio sources, and redshifts for nine of them. Seven have redshifts in excess of 1, with the highest being 1.841 for 3C 454.1; the remaining three sources are also likely to be at z > 1. One of the newly identified sources, 3C 194, shows a moderately strong Lyα emission, and may be a member of the new class of objects, possible young/forming galaxies, typified by 3C 326.1 and 3C 294. The optical identifications of the 3CR sources are now complete, and only six are lacking redshifts. Practically all of the new identifications are galaxies whose light appears to be dominated by stars, rather than nonthermal active nuclei, although their powerful radio emission argues that they are likely to be highly unusual objects. Their observed properties are similar to those of previously identified high-redshift powerful radio galaxies.
