Large Scale Structure in the ELAIS S1 Survey
E. A. Gonzalez-Solares, S. Oliver, C. Gruppioni +6
We present an analysis of the two-point angular correlation function of the ELAIS S1 survey. The survey covers 4 deg and contains 462 sources detected at 15m to a 5 flux…
The HELLAS2XMM 1dF survey: on the nature of high X-ray to optical flux ratio sources
F. Fiore, M. Brusa, F. Cocchia +12
We present results from the photometric and spectroscopic identification of 122 X-ray sources discovered by XMM-Newton in the 2-10 keV band (the HELLAS2XMM 1dF sample). One of the…
The Hellas2XMM survey: III. Multiwavelength observations of hard X-ray selected sources in the PKS 0312-77 field
M. Brusa, A. Comastri, M. Mignoli +11
We present extensive optical, radio and infrared follow-up observations of a sample of 35 hard X-ray (2-10 keV) selected sources discovered serendipitously in the PV XMM-Newton obs…
The HELLAS2XMM survey: IV. Optical identifications and the evolution of the accretion luminosity in the Universe
F. Fiore, M. Brusa, F. Cocchia +12
We present results from the photometric and spectroscopic identification of 122 X-ray sources recently discovered by XMM-Newton in the 2-10 keV band (the HELLAS2XMM 1dF sample). Th…
The Radio/Mid-Infrared Correlation and the Contribution of 15-micron Galaxies to the 1.4-GHz Source Counts
C. Gruppioni, F. Pozzi, G. Zamorani +6
The radio counterparts to the 15-micron sources in the European Large Area ISO Survey southern fields are identified in 1.4-GHz maps down to about 80 microJy. The radio-MIR correla…
The BeppoSAX High Energy Large Area Survey (HELLAS) - VI. The radio properties
P. Ciliegi, C. Vignali, A. Comastri +3
We present results of a complete radio follow-up obtained with the VLA and ATCA radio telescopes down to a 6 cm flux limit of about 0.3 mJy of all the 147 X-ray sources detected in…
