[2.17] Ionised Iron Lines in X-ray Reflection Spectra

D.R. Ballantyne (IoA), R.R. Ross (IoA & College of the Holy Cross), A.C. Fabian (IoA)

We present results from new calculations of the reflected X-ray spectrum from ionised accretion disks in Active Galactic Nuclei (AGN). These calculations improve on our previous models by including the condition of hydrostatic balance in the vertical direction, following the work of Nayakshin, Kazanas & Kallman (2000). Our results show that, for gas pressure dominated accretion discs, ionised iron features are found in the reflection spectrum over a range of conditions. We also explore extending our results into radiation pressure dominated discs, and discuss the limitations of the current models.
