The BeppoSAX High Energy Large Area Survey -V. The nature of the hard X-ray source populations and its evolution
F. La Franca, F. Fiore, C. Vignali +7
We present optical spectroscopic identifications of hard X-ray (5-10 keV) selected sources belonging to the HELLAS sample obtained with BeppoSAX down to a 5-10 keV flux limit of f_…

The Chandra Deep Field North Survey. X. X-ray Emission from Very Red Objects
D. M. Alexander, C. Vignali, F. E. Bauer +4
The multi-wavelength properties of Very Red Objects (VROs; I-K>=4) are largely unknown as many of these sources are optically faint (I>=24) and undetected at most wavelengths. Here…

The HELLAS2XMM survey: I. The X-ray data and the Log(N)-Log(S)
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 detect a total of 1022, 495 and 100 sources, down to…
