Metal abundances and excitation of extranuclear clouds in the Circinus galaxy -- A new method for deriving abundances of AGN narrow line clouds
E. Oliva, A. Marconi, A. F. M. Moorwood
Spectra of extranuclear clouds within the ionization cone of Circinus galaxy are presented and modelled assuming photoionization by the Seyfert 2 nucleus but no preconceived assump…
