On the Simbol-X capability of detecting red/blue-shifted emission and absorption Fe K lines
F. Tombesi, M. Cappi, G. Ponti +2
The detection of red/blue-shifted iron lines in the spectra of astronomical X-ray sources is of great importance, as it allows to trace the environment around compact objects, like…
An XMM-Newton Survey of Ultra-Luminous Infrared Galaxies
V. Braito, A. Franceschini, R. Della Ceca +8
We present preliminary results of XMM-Newton observations of 5 Ultra-luminous Infrared Galaxies (ULIRGs), part of a mini-survey program dedicated to 10 ULIRGs selected from the bri…
First Results from a XMM-Newton Survey of a Distance-Limited (D<22 Mpc) Sample of Seyfert Galaxies: I- the Agns
M. Cappi, G. Di Cocco, F. Panessa +18
We report here preliminary results from a survey of nearby Seyfert galaxies using the EPIC CCDs on board XMM-Newton. The total sample consists of 28 Seyfert galaxies, and constitut…
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…
