Descripción
Results of CCD photometry of the three low-luminosity radio galaxies
which contain jets at the kpc scale: B2 0836 + 29, B2 2116 + 26, and B2
2236 + 35 are presented and discussed. The photometric properties of the
galaxies are examined by analyzing the radial variations of surface
brightness, ellipticity, major axis position angle, and isophote center.
The deviations of the isophotes are characterized from perfect
elliptical contours. The morphological properties of the galaxies are
discussed in terms of their local environment and radio emission. The
galaxies are found to present optical peculiarities that are signatures
of merging processes or interactions. When galaxy models are subtracted
to the original frames, the resulting residual images make it possible
to put limits on the radio to optical spectral indices of the jets. It
is inferred that the synchrotron spectra of these jets have cutoff
frequencies below 5 x 10 exp 14 Hz.
