Broad Band X-Ray Observations of the Narrow Line X-Ray Galaxy NGC 5506
T. G. Wang, T. Mihara, C. Otani +2
We present a detailed analysis of broad band X-ray data of the Seyfert 2 galaxy NGC5506. 2-10 keV band are detected during a 1-day ASCA observation, while no significant change in…
The Complex X-ray Spectrum of 3C 273: ASCA Observations
M. Cappi, M. Matsuoka, C. Otani +1
shortened) Results obtained from 9 X-ray observations of 3C 273 performed by ASCA are presented (for a total exposure time of about 160 000 s). The analysis and interpretation of t…
The variable OVIII Warm Absorber in MCG-6-30-15
C. Otani, T. Kii, C. S. Reynolds +8
We present the results of a 4 day ASCA observation of the Seyfert galaxy MCG-6-30-15, focussing on the nature of the X-ray absorption by the warm absorber, characterizd by the K-ed…
On broad iron K-alpha lines in Seyfert 1 galaxies
A. C. Fabian, K. Nandra, C. S. Reynolds +5
The X-ray spectrum obtained by Tanaka et al from a long observation of the active galaxy MCG shows a broad iron K line skewed to low energies. The simplest interpretat…
