Physical interpretation of the UV/X-ray variability behavior of NGC 7469
P. O. Petrucci, L. Maraschi, F. Haardt +1
We present a re-analysis of the simultaneous 30 day IUE/XTE observation of NGC 7469 done in 1996. Our main progress, in comparison to previous spectral analysis, is to adopt and fi…
SIMBOL-X : a new generation hard X-ray telescope
P. Ferrando, M. Arnaud, B. Cordier +17
SIMBOL-X is a hard X-ray mission, operating in the 0.5-70 keV range, which is proposed by a consortium of European laboratories for a launch around 2010. Relying on two spacecraft…
The XMM/BeppoSAX observation of Mkn 841
P. O. Petrucci, C. Cabanac, G. Henri +9
Mkn 841 has been observed simultaneously by XMM and BeppoSAX in January 2001. Due to operational contingency, the 30ks XMM observation was split into two parts, separated by about…
Spectral analysis of a large sample of BeppoSAX Seyfert spectra with Comptonization models: Preliminary results
P. O. Petrucci, M. Dadina
We present preliminary results of the spectral analysis of a large sample of Seyfert galaxies observed by BeppoSAX. The only selection criterium was a sufficiently large S/N ratio…
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…
