X-ray obscuration and obscured AGN in the local universe
M. Guainazzi, G. Matt, G. C. Perola
In this paper we discuss the X-ray properties of 49 local (z<0.035) Seyfert 2 galaxies with HST/WFC2 high-resolution optical coverage. It includes the results of 26 still unpublish…
On the transmission- to reprocessing-dominated spectral state transitions in Seyfert 2 galaxies
M. Guainazzi, A. C. Fabian, K. Iwasawa +2
We present Chandra and XMM-Newton observations of a small sample (11 objects) of optically-selected Seyfert~2 galaxies, for which ASCA and BeppoSAX had suggested Compton-thick obsc…
The complex 0.1-200 keV spectrum of the Seyfert 1 Galaxy NGC4593
M. Guainazzi, G. C. Perola, G. Matt +5
We report on the first observation of the Seyfert 1 galaxy NGC4593 in the 0.1-200 keV band, performed with the BeppoSAX observatory. Its spectral components are for the first time…
BeppoSAX confirms extreme relativistic effects in the X-ray spectrum of MCG-6-30-15
M. Guainazzi, G. Matt, S. Molendi +8
We report the first simultaneous measure of the X-ray broadband (0.1--200 keV) continuum and of the iron K-alpha fluorescent line profile in the Seyfert 1 galaxy MCG-6-30-15. Our d…
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…
1H0419-577: A "two-state" soft X-ray Seyfert galaxy
M. Guainazzi, A. Comastri, G. M. Stripe +8
In this paper we report on the first simultaneous optical and X-ray (Beppo-SAX) observations of the radio-quiet AGN 1H0419-577. The optical spectrum clearly leads us to classify th…
