Session 50 - Active Galaxies.
Display session, Tuesday, January 16
North Banquet Hall, Convention Center
We report the results of radio, optical, and IR observations of a sample of southern Seyfert galaxies in an ongoing multi-wavelength study of the circumnuclear star-formation properties of AGNs. The radio data consist of Australian Telescope Compact Array (ATCA) continuum maps at 13, 6, and 3 cm. The optical and IR data are long slit CCD spectra obtained at the Anglo-Australian Telescope (AAT). Our approach is to map the distribution and strength of various key optical and IR emission lines across the face of the galaxies in order to distinguish between regions of star-formation and extended narrow-line regions (ENLR) and to compare the optical and IR emission with the position of the radio continuum flux, flux densities, and spectral indices to get a handle on the various emission mechanisms present in the AGNs and in the circumnuclear environments of AGNs.
