Effects of Kerr Spacetime on Spectral Features from X-Ray Illuminated Accretion Discs
A. Martocchia, V. Karas, G. Matt
We performed detailed calculations of the relativistic effects acting on both the reflection continuum and the iron line from accretion discs around rotating black holes. Fully rel…
Mapping the circumnuclear matter of NGC1068 in X-rays
M. Guainazzi, S. Molendi, P. Vignati +2
An-energy dependent variation of the X-ray emission from the archetypical "Compton-thick'' Seyfert 2 galaxy NGC1068 has been observed between two BeppoSAX observations, performed o…
Inner accretion disk disappearance during a radio flare in GRS 1915+105
M. Feroci, G. Matt, G. Pooley +3
Simultaneous X-ray (BeppoSAX, 0.1-300 keV) and radio (Ryle Telescope, 15 GHz) observations of the superluminal galactic source GRS 1915+105 in high flux state were carried out star…
Broad band spectral properties of Seyfert 1 galaxies observed with BeppoSAX
L. Piro, A. De Rosa, M. Dadina +8
We will present some results on the broad--band observations of BeppoSAX of the bright Seyfert galaxies NGC 4151 and NGC 5548.
A Qualitative Test of a Unified Model of Seyfert Galaxies with BeppoSAX
M. Cappi, L. Bassani, G. Malaguti +1
The broad band 0.1-200 keV spectra of a sample of 5 Seyfert 2 galaxies (NGC 7172, Mkn 3, NGC 2110, NGC 4507 and NGC 7674) have been measured within the first year of the …
BeppoSAX observations of Mkn 3: Piercing through the torus of a Seyfert 2 galaxy
M. Cappi, L. Bassani, A. Comastri +15
A new BeppoSAX broad-band (0.6-150 keV) spectrum of the Seyfert 2 galaxy Mkn 3 is presented. The spectrum provides a direct measurement of a large, neutral column of gas with Nh~10…
