Overdensity of X-Ray sources near 3C 295: a candidate filament
V. D'Elia, F. Fiore, F. Cocchia
We present a statistical analysis of the Chandra observation of the source field around the 3C 295 galaxy cluster (z=0.46) aimed at the search for clustering of X-ray sources. Thre…
The Faint X-ray Source Population Near the 3C 295 cluster
V. D'Elia, F. Fiore, M. Elvis +5
We present a statistical analysis of the Chandra observation of the source field around the 3C 295 galaxy cluster (z=0.46). Three different methods of analysis, namely a chip by ch…
High Energy Large Area Surveys: optically obscured AGN and the history of accretion
F. Fiore, the HELLAS2XMM collaboration
Hard X-ray, large area surveys are a fundamental complement of ultra-deep, pencil beam surveys in obtaining a more complete coverage of the L-z plane, allowing to find luminous QSO…
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 Far Ultraviolet Spectroscopic picture of the Missing Baryons in the Local Group
F. Nicastro, A. Zezas, M. Elvis +6
The number of detected baryons in the low-redshift Universe (z < 1) is far small er than the corresponding number of baryons observed at higher redshift. According to hydrodynamica…
Spectral properties of faint hard X-ray selected sources
E. Piconcelli, L. Bassani, M. Cappi +3
We present preliminary results from a XMM-Newton spectroscopic survey of hard (2 -10 keV) X-ray sources detected serendipitously in seven EPIC FOVs. All observations were performed…
