ASCA detection of the FeK edge in the spectrum of the Seyfert 2 galaxy IRAS 04575-7537: a sign of a complex absorber
C. Vignali, A. Comastri, G. M. Stirpe +5
ASCA X-ray spectral analysis of the Seyfert 2 galaxy IRAS 04575-7537 is presented. The main result is the presence of a significant iron edge at a rest energy of 7.13^+0.21_-0.16 k…
BeppoSAX observation of NGC 7674: a new reflection-dominated Seyfert 2 galaxy
G. Malaguti, G. G. C. Palumbo, M. Cappi +6
The Seyfert 2 galaxy NGC 7674 has been observed within the BeppoSAX Core Programme with the onboard narrow field instruments between 0.1 and 100 keV. The broad-band spectrum shows…
ASCA and ROSAT X-ray Spectra of IC 5063 and NGC 3998
C. Vignali, A. Comastri, M. Cappi +1
The results of the 0.1-10 keV spectral analysis of IC 5063 (Narrow Line Radio Galaxy) and NGC 3998 (LINER) are presented. In both cases there is evidence of a FeK emission line,…
The First High-Energy X-Ray Spectrum of a Z Radio-Quiet Quasar: Q1101-264
C. Vignali, A. Comastri, M. Cappi +1
Results of the X-ray spectral analysis of the high-redshift radio-quiet quasar Q1101-264 are presented. The ASCA spectrum suggests a marginal evidence of a FeK emission line at…
