X-ray spectral evolution of GS 2023+338 (V404 Cyg) during decline after outburst
P. Zycki, C. Done, D. Smith
We have re-analyzed archival GINGA data of the soft X-ray transient source GS2023+308 (V404 Cyg) covering the decline phase of its May 1989 outburst. Our spectral modelling include…
X-ray and soft gamma-ray spectra of Broad-Line Radio Galaxies
Przemyslaw R. Wozniak, Andrzej A. Zdziarski, David Smith +2
We study X-ray and soft gamma-ray spectral properties of BLRGs using data from Ginga, ASCA, OSSE and EXOSAT. The X-ray spectra are well fitted by an intrinsic power-law continuum w…
The broad-band X-ray spectrum of Mrk 3
R. G. Griffiths, R. S. Warwick, I. Georgantopoulos +2
We have used non-simultaneous Ginga, ASCA and ROSAT observations to investigate the complex X-ray spectrum of the Seyfert 2 galaxy Mrk 3. We find that the composite spectrum can be…
Evolution of the accretion flow in Nova Muscae 1991
Piotr Zycki, Chris Done, David Smith
We identify the X-Ray reflected component in the Ginga spectra of Nova Muscae 1991, a Black Hole transient system used as the prototype for the recent model of Esin, McClintock & N…
