Multiple X-ray reflection from ionized slabs
R. R. Ross, A. C. Fabian, D. R. Ballantyne
Multiple reflection of X-rays may be important when an accretion disc and its hot corona have a complicated geometry, or if returning radiation due to gravitational light bending i…
Reflection Spectra from Photoionized Accretion Discs
D. R. Ballantyne, R. R. Ross, A. C. Fabian
We review recent progress on the modeling and use of reflection spectra from irradiated and ionized accretion discs. On the computational side, calculations of reflection spectra f…
Soft X-ray emission lines from photoionized accretion discs: constraints on their strength and width
D. R. Ballantyne, R. R. Ross, A. C. Fabian
We consider the properties of soft X-ray emission lines in the reprocessed emission from a photoionized accretion disc. Observations of these lines will be important in determining…
The response of the Fe Kαline to changes in the X-ray illumination of accretion discs
D. R. Ballantyne, R. R. Ross
X-ray reflection spectra from photoionized accretion discs in active galaxies are presented for a wide range of illumination conditions. The energy, equivalent width (EW) and flux…
On the hard X-ray spectra of radio-loud active galaxies
D. R. Ballantyne, R. R. Ross, A. C. Fabian
Over the last few years X-ray observations of broad-line radio galaxies (BLRGs) by ASCA, RXTE and BeppoSAX have shown that these objects seem to exhibit weaker X-ray reflection fea…
