Transmission- to reflection-dominated transition in Seyfert 2 galaxies: the XMM-Newton view
M. Guainazzi, P. Rodriguez-Pascual, A. C. Fabian +3
In this paper we present the current status of a XMM-Newton program to observe an optically-defined, complete and unbiased sample of Compton-thick Seyfert 2 galaxies. The main goal…
Exploring the spectral properties of faint hard X-ray sources with XMM-Newton
E. Piconcelli, M. Cappi, L. Bassani +3
We present a spectroscopic study of 41 hard X-ray sources detected serendipitously with high significance (> 5 sigma in the 2-10 keV band) in seven EPIC performance/verification ph…
Compton reflection and iron fluorescence in BeppoSAX observations of Seyfert type 1 galaxies
G. C. Perola, G. Matt, M. Cappi +5
A sample of nine bright Seyfert 1 and NELG type galaxies, observed with BeppoSAX, is analyzed to assess on a truly broad band basis (0.1-200 keV) the issue of the spectral contribu…
The Phoenix galaxy: UGC4203 re-birth from its ashes?
M. Guainazzi, G. Matt, F. Fiore +1
We report on a dramatic transition between a Compton-thick, reflection-dominated state and a Compton-thin state in the Seyfert 2 galaxy UGC4203, discovered by comparing a recent (M…
The BeppoSAX broad-band spectrum and variability of the Seyfert 1 NGC 3783
A. De Rosa, L. Piro, F. Fiore +5
BeppoSAX observed the Seyfert 1 galaxy NGC 3783 for ~ 5 days from 1998 June 6 to 1998 June 10. The average flux during the observation was F(2-10 keV) ~ 6 X 10^{-11} erg cm^-2 s^-1…
The log(N)-log(S) and the Broadband Properties of the Sources in the HELLAS2XMM Survey
A. Baldi, S. Molendi, A. Comastri +3
We present the first results from an XMM-Newton serendipitous medium-deep survey, which covers nearly three square degrees. We show the log(N)-log(S) distributions for the 0.5-2, 2…
