The radio observations show that the sidedness distribution of the radio jets is consistent with Doppler boosting with a typical Lorentz factor gamma=5. The fading of the jets is consistent with adiabatic jet expansion losses. The optical imaging indicates that the galaxies typically resemble normal ellipticals except for the presence of small (approx. 1 arcsec) central disks or lanes of dust and emission gas. Disks have outlines which closely resemble ellipses, while lanes are warped filaments. Disks are invariably well aligned with the stellar major axis while lanes are not. We describe possible scenarios to explain these differences. Half of the nuclei show unresolved nuclear blue emission. We argue this is synchrotron emission from the inner jet. The STIS spectral observations form an on-going program. So far ten targets have been observed. Multiple-slit high resolution spectra are obtained to infer to what extent the emission gas moves on circular orbits, and hence provide a measurement of the mass of the central black hole. In a few cases low resolution spectra are obtained to determine emission-line ratios to constrain the ionization mechanism of the gas: photo- or shock-ionization.
Combining the results from radio and optical data we present
preliminary results on: (1) the jet orientation, physics and bulk
outflow speed of the radio plasma, (2) the relationship between black
hole mass, radio luminosity, optical line and nuclear continuum
fluxes, (3) limits on the mass accretion rate, (4) the relationship
between BL Lac objects and low luminosity radio galaxies.
