R. ; van Breugel, W. ; Miley, G. K. Abstract Optical observations of the radio jet galaxies 3C 66 B, 3C 31, NGC 315, and 3C 449 are reported. Optical counterparts to the inner regions of the radio jets are seen in 3C 66 B and 3C 31, and upper limits are set for optical jets in the other two. The ratios of optical to radio emission in the jets of 3C 66 B and 3C 31 are only slightly less than that for M87, and the limits set for NGC 315 and 3C 449 are consistent with fairly similar ratios of optical to radio emission. These measurements suggest that a continuous nonthermal spectrum extending from 10 to the 9th to 10 to the 15th Hz is a general property of jets. The jet parameters are considered in relation to the intrinsic properties of the galaxies and the associated extended radio emission. Implications for models of energy transport in radio sources are discussed. Significant amounts of interstellar matter are observed in each of the four galaxies, indicating that models for jets which involve an interaction with the interstellar medium may be most appropriate.
