Edge (Durham, UK), Nectaria A. B. Gizani (Ioannina, Greece), Peter N. Wilkinson (Manchester, UK), Ismael Perez-Fournon (La Laguna, Spain | | Abstract: | We are conducting a multi-wavelength (radio, optical, and X-ray) observational campaign to classify, morphologically and physically, a sample of 55 flat-spectrum radio sources dominated by structure on kpc-scales. This sample contains 22 compact-/medium-sized symmetric object candidates, a class of objects thought to be the early stages of the evolution of radio galaxies. The vast majority of the remaining objects have core-plus-one-sided-jet structures, half of which present sharply bent jets, probably due to strong interactions with the interstellar medium of the host galaxies. Once the observational campaign is completed, we will constrain evolutionary theories of radio galaxies at their intermediate stages and possibly understand the physics of the hypothesized narrow line region in active galactic nuclei, given our advantageous statistical position. | | Source: | arXiv, astro-ph/9910183 | | Services: | Forum | Review | PDF | Favorites | |
