31 Dec 2002 | | Journal: | New Astron.Rev. 47 (2003) 261-265 | | Subject: | astro-ph | | Affiliation: | 1,2), C. N. Tadhunter , R. Morganti ( Sheffield, Kapteyn Institute, Groningen, Astron | | Abstract: | We demonstrate the efficiency of high quality optical spectroscopic observations of two compact radio sources, PKS 1549-79 and PKS 1345+12, as a probe of the kinematics and physical conditions in the circumnuclear gas in the early stages of radio source evolution. We outline a schematic model for PKS 1345+12 based on the model for PKS 1549-79 proposed by Tadhunter et al. (2001) in which the young radio source is expanding through a dense and dusty enshrouding cocoon, sweeping material out of the circumnuclear regions. | | Source: | arXiv, astro-ph/0301642 | | Services: | Forum | Review | PDF | Favorites | |
