On the influence of resonant absorption on the iron emission line profiles from accreting black holes
Mateusz Ruszkowski, Andrew C. Fabian
The fluorescent iron K emission line profile provides an excellent probe of the innermost regions of active galactic nuclei. Fe XXV and Fe XXVI in diffuse plasma above the accre…

X-ray iron line variability for the model of an orbiting flare above a black hole accretion disc
Mateusz Ruszkowski
The broad X-ray iron line, detected in many active galactic nuclei, is likely to be produced by fluorescence from the X-ray illuminated central parts of an accretion disc close to…

ROSAT HRI Monitoring of Extreme X-ray Variability in the Narrow-Line Quasar PHL 1092
W. N. Brandt, Th. Boller, A. C. Fabian +1
We report results from an 18-day ROSAT HRI monitoring campaign on the ultrasoft Narrow-Line Seyfert 1 (NLS1) class quasar PHL 1092. This luminous, radio-quiet quasar showed strong…
