[O-II] AND CONTINUUM STRUCTURE IN RADIO-LOUD QSOS TO Z=0.9

Images have been obtained in R band and redshifted 100A band [O II] with the High Resolution Camera of the Canada-France-Hawaii Telescope. Ten quasi-stellar objects were observed, with redshifts from 0.36 to 0.91, with radio structures ranging from unresolved to large double-lobed. The images have a mean full width at half maximum 0.64 arcsec, and a spread from 0.45 to 0.80. Extended emission line structure is seen in all cases, with a variety of properties. In particular, in four of the six large radio sources, the emission line gas appears to be associated with the radio structure. However, the connection between radio and emission line structure is not as marked as in radio galaxies, and no large emission line regions are seen. The continuum images are resolved in six of the nine cases, four of which are at redshifts larger than 0.8. The evolution of the sources is discussed.
