Galactic Black HOle Binary Systems
C. Done
I review observations of the X-ray spectra of Galactic Black Hole Candidates, and theoretical ideas as to how these can be produced. X-ray reflection should enable different source…
Probing the Inner Region of Cyg X-1 in the Low/Hard State through its X-ray Broad Band Spectrum
T. Di Salvo, C. Done, P. T. Zycki +2
We present the broad band X-ray spectrum of Cyg X-1 in the low/hard state as observed by the instruments on board of BeppoSAX. The spectrum spans from 0.1 to 200 keV, allowing the…
Structure of the Circumnuclear Region of Seyfert 2 Galaxies Revealed by RXTE Hard X-ray Observations of NGC 4945
G. M. Madejski, P. T. Zycki, C. Done +4
We report the Rossi X-ray Timing Explorer observations of the heavily absorbed Seyfert 2 galaxy NGC 4945, which confirm the large column density of the absorber, corresponding to t…
The relativistic iron line profile in the Seyfert 1 Galaxy IC4329a
C. Done, G. M. Madejski, P. T. Zycki
We present simultaneous ASCA and RXTE data on the bright Seyfert 1 galaxy IC4329a. The iron line is significantly broadened, but not to the extent expected from an accretion disk w…
