Abstract

X-ray reflection spectra are an important component in the X-ray spectra of many active galactic nuclei and Galactic black hole candidates. It is likely that reflection takes place from highly ionized surfaces of the accretion disc in some cases. this can lead to strong Comptonization of the emergent iron, and other absorption and emission features. We present such reflection spectra here, computed in a self-consistent manner with the method described by Ross & Fabian. In particular we emphasize the range where the ionization parameter (the flux to density ratio) xi is around and above 10(4). Such spectra may be relevant to the observed spectral features found in black hole candidates such as Cygnus X-l in the low/hard state.
