XMM-Newton Survey of a Distance-limited Sample of Seyfert Galaxies: Preliminary Spectral Results
M. Cappi, G. Di Cocco, F. Panessa +19
An unbiased estimate of the average intrinsic X-ray properties and column density distribution of Seyfert galaxies in the local Universe is crucial to validate unified models of ac…
BeppoSAX uncovers the hidden Seyfert 1 nucleus in the Seyfert 2 galaxy NGC 2110
G. Malaguti, L. Bassani, M. Cappi +11
The Seyfert 2 galaxy NGC 2110 has been observed with BeppoSAX between 0.5 and 150 keV. The high energy instrument onboard, PDS, has succeeded in measuring for the first time the sp…
BeppoSAX Observations of Bright Seyfert 2 Galaxies: Measuring the Intrinsic Continuum Emission
L. Bassani, M. Cappi, G. Malaguti +19
We report broad band (0.1-200 keV) X-ray observations, made by BeppoSAX, of a sample of bright Seyfert 2 galaxies: NGC7172, NGC2110, NGC4507, Mkn 3 and NGC7674. These spectra provi…
Hard X--ray detection of NGC 1068 with BeppoSAX
G. Matt, M. Guainazzi, F. Frontera +14
We report on the first detection above ~10 keV of the archetypal Compton-thick Seyfert 2 galaxy NGC 1068. This detection, obtained with the PDS instrument onboard BeppoSAX in the 2…
