Infrared spectroscopy of young supernova remnants heavily interacting with the interstellar medium
E. Oliva, A. F. M. Moorwood, S. Drapatz +2
ISO spectral observations of the supernova remnant RCW103 are presented. This object is the prototype of relatively young remnants with fast shocks interacting with dense interstel…
ISO-SWS spectroscopy of IC443 and the origin of the IRAS 12 and 25 micron emission from radiative supernova remnants
E. Oliva, D. Lutz, S. Drapatz +1
ISO-SWS spectral observations of the supernova remnant IC443 are presented. Like other radiative SNRs, this object is characterized by prominent line-emitting filaments and relativ…
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…
Spectropolarimetry of the Circinus Galaxy
E. Oliva, A. Marconi, A. Cimatti +1
High quality 4500-6800 A spectropolarimetric observations of the Circinus galaxy are reported. These show polarized and relatively broad (FWHM~3300 km/s) Halpha (as well as margina…
