Modelling of the X-ray broad absorption features in Narrow-Line Seyfert 1s
D. Porquet, M. Mouchet, A. -M. Dumont
We investigate the origin of the broad absorption features detected near 1-1.4 keV in several Narrow Line Seyfert 1 galaxies, by modelling the absorbing medium with various physica…
BeppoSAX observations of AM Herculis in intermediate and high states
G. Matt, D. de Martino, B. T. Gaensicke +5
Temporal and spectral analyses from BeppoSAX observations of AM Her performed during both an intermediate and a high state are presented and discussed. Optical observations taken a…
X-ray emitting-absorbing media in Seyfert 1 galaxies
M. Mouchet, A. Abrassart, D. Porquet +2
Seyfert galaxies have been shown to exhibit a large variety of features in their X-ray spectra from which the environment of the central engine can be deduced. We focus on the two…
Accretion and Emission Processes in AGN: the UV-X Connection
S. Collin, A. Abrassart, B. Czerny +2
The main characteristics of the average spectrum of radio quiet AGN in the UV and X-ray range are reviewed, and the emission mechanisms are discussed in the framework of accretion…
