A rapidly variable narrow X-ray iron line in Mkn 841
P. O. Petrucci, G. Henri, L. Maraschi +8
We report on the detection of a rapidly variable narrow Fe K line in Mkn 841. The source has been observed two times by XMM-Newton and simultaneously with BeppoSAX. The two obse…
Are quasars accreting at super-Eddington rates?
S. Collin, C. Boisson, M. Mouchet +4
In a previous paper, Collin & Huré (2001), using a sample of Active Galactic Nuclei (AGN) where the mass has been determined by reverberation studies (Kaspi et al. 2000), have show…
Reprocessing of X-rays in AGN. I. Plane parallel geometry -- test of pressure equilibrium
A. -M. Dumont, B. Czerny, S. Collin +1
We present a model of the vertical stratification and the spectra of an irradiated medium under the assumption of constant pressure. Such a solution has properties intermediate bet…
The structure and radiation spectra of illuminated accretion discs in AGN. I. Moderate illumination
A. Różańska, A. -M. Dumont, B. Czerny +1
We present detailed computations of the vertical structure of an accretion disc illuminated by hard X-ray radiation with the code {\sc titan-noar} suitable for Compton thick media.…
