Abstract | Medium-wide-band photometry is presented of the integrated light of the southern radio galaxy NGC 5128. Observations span the range 1550 A to 4250 A. The energy distribution of NGC 5128 is compared with those of other radio galaxies, NGC 1316 and NGC 4472, for which similar photometry has recently been reported. A satisfactory match to the observations is achieved by a population model based on OAO photometry of gala ... |
