X-ray He-like ions diagnostics: New Computations for Photoionized Plasmas: I. preliminary considerations
Séverine Coupé, Olivier Godet, A. -M. Dumont +1
Using the new version of the photoionization code Titan designed for plane-parallel photoionized thick hot media, which is unprecedented from the point of view of line transfer, we…

Escape probability methods versus "exact" transfer for modelling the X-ray spectrum of Active Galactic Nuclei and X-ray binaries
A-M. Dumont, S. Collin, F. Paletou +3
In the era of XMM-Newton and Chandra missions, it is crucial to use codes able to compute correctly the line spectrum of X-ray irradiated thick media (Thomson thickness of the orde…

Evolution of the X-ray spectrum in the flare model of Active Galactic Nuclei
S. Collin, S. Coupé, A-M. Dumont +2
Nayakshin & Kazanas (2002) have considered the time-dependent illumination of an accretion disc in Active Galactic Nuclei, in the lamppost model. We extend their study to the flare…
