SSC of MAXI experiment
M. Sakano, H. Tomida, M. Matsuoka +16
Monitor of All-sky X-ray Image (MAXI) on the International Space Station (ISS) has two kinds of X-ray detectors: the Gas Slit Camera (GSC) and the Solid-state Slit Camera (SSC). SS…
First ASCA results for high-redshift Radio-Quiet Quasars
C. Vignali, A. Comastri, M. Cappi +2
Here we report the X-ray spectral analysis of 5 high-redshift () radio-quiet quasars (RQQs) observed with the ASCA satellite. A simple power law with Galactic absorption…
The broad band X-ray spectra of intermediate BL Lac objects
J. Siebert, W. Brinkmann, S. A. Laurent-Muehleisen +1
We present recent X-ray observations of intermediate BL Lac objects (IBLs), i.e. BL Lacs which are located between high-energy and low-energy peaked BL Lac objects with respect to…
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…
Results from Monitoring the Broad-Line Radio Galaxy 3C 390.3
K. M. Leighly, M. Dietrich, E. Waltman +6
During 1995, the broad-line radio galaxy 3C 390.3 is the subject of a multi-wavelength monitoring campaign comprised of ROSAT HRI, IUE, and ground based optical, infrared and radio…
