An XMM-Newton Study of Hard X-ray Sources
E. Piconcelli, L. Bassani, M. Cappi +3
We briefly report on an on-going spectroscopic study of hard X-ray sources selected serendipitously in 12 XMM-Newton fields. Results for the analysis of the 41 sources from the fir…
XMM-NEWTON Observation of the Seyfert 2 Galaxy NGC 4138
L. Foschini, F. Panessa, A. L. Longinotti +9
The XMM-Newton data presented here are the first X-ray observation of the Seyfert 2 galaxy NGC4138. Although the galaxy has been pointed by ROSAT-HRI, it was not detected, with a f…
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…
XMM-Newton Detection of a Comptonized Accretion Disc in the Quasar PKS0558-504
P. T. O'Brien, J. N. Reeves, M. J. L. Turner +6
We present XMM-Newton observations of the bright quasar PKS0558-504. The 0.2-10 keV spectrum is dominated by a large, variable soft X-ray excess. The fastest flux variations imply…
