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…
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…
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…
First Results from the MECS on board BeppoSAX
S. Molendi, L. Chiappetti, G. Cusumano +12
In this contribution we discuss briefly a few calibration items relevant to the data analysis and present some preliminary scientific results. The discussion on instrumental topics…
