XMM-Newton observation of the Lockman Hole II. Spectral analysis
V. Mainieri, J. Bergeron, G. Hasinger +5
We present the results of the X-ray spectral analysis of the first deep X-ray survey with the XMM-Newton observatory during Performance Verification. We restrict the analysis to th…
The BeppoSAX view of the X-ray active nucleus of NGC4258
F. Fiore, S. Pellegrini, G. Matt +9
BeppoSAX observed NGC4258 on December 1998, when its 2-10 keV luminosity was \~1E41 erg/s. 100% variability is observed in the 3-10 keV band on timescales of a half a day while 20%…
The European Large Area ISO Survey V: a BeppoSAX hard X-ray survey of the S1 region
D. M. Alexander, F. La Franca, F. Fiore +18
We present BeppoSAX observations of the Southern S1 region in the European Large Area ISO Survey (ELAIS). These observations cover an area of ~1.7 sq. deg. and reach an on-axis (~0…
A FIRST DETERMINATION OF THE SURFACE DENSITY OF GALAXY CLUSTERS AT VERY LOW X--RAY FLUXES
P. Rosati, R. Della Ceca, R. Burg +2
We present the first results of a serendipitous search for clusters of galaxies in deep ROSAT-PSPC pointed observations at high galactic latitude. The survey is being carried out u…
