H. ; Fomalont, E. B. ; Palimaka, J. J. ; Willis, A. G. Abstract The radio galaxy 3C 277.3 has been mapped at about 1 arcsec resolution using the VLA at 4885 MHz. Its structure resembles that of the inner 50 arcsec of the radio emission from M87. A bridge or jet linking the unresolved central radio core to the southern lobe contains two bright radio knots. One of these coincides with a blue polarized continuum knot in the envelope of the galaxy. Minimum energy calculations for this knot demand in situ particle deposition there, as in the M87 optical-radio jet. If the flow velocity through the knots is of the same order as the 200-300 km/s peculiar radial velocity of an optical emission-line system detected in their vicinity by Miley et al. (1981), two interpretations are possible. Either the magnetic field in the knots is well below its equipartition value, or in situ particle deposition occurs far from the radio core, and a large mass flux through the knots is needed to supply the observed luminosity of the source.
