The HELLAS2XMM survey: XI. Unveiling the nature of X-ray Bright Optically Normal Galaxies
F. Civano, M. Mignoli, A. Comastri +8
X-ray Bright Optically Normal Galaxies (XBONGs) constitute a small but not negligible fraction of hard X-ray selected sources in recent Chandra and XMM-Newton surveys. Even though…
The host galaxy of GRB031203: a new spectroscopic study
R. Margutti, G. Chincarini, S. Covino +11
The host galaxy of the long-duration gamma-ray burst (GRB) 031203 (HG031203) offers a precious opportunity to study in detail the environment of a nearby GRB. The aim is to better…
AGN counts at 15um. XMM observations of the ELAIS-S1-5 sample
F. La Franca, S. Puccetti, N. Sacchi +7
Context: The counts of galaxies and AGN in the mid infra-red (MIR) bands are important instruments for studying their cosmological evolution. However, the classic spectral line rat…
A Photometrically Detected Forming Cluster of Galaxies at Redshift 1.6 in the GOODS Field
M. Castellano, S. Salimbeni, D. Trevese +9
We report the discovery of a localized overdensity at z~1.6 in the GOODS-South Field, presumably a poor cluster in the process of formation. The three-dimensional galaxy density ha…
An X-ray Survey in SA 57 with XMM-Newton
D. Trevese, F. Vagnetti, S. Puccetti +3
The maximum number density of Active Galactic Nuclei (AGNs), as deduced from X-ray studies, occurs at z<~1, with lower luminosity objects peaking at smaller redshifts. Optical stud…
X-ray source counts in the COSMOS field
N. Cappelluti, G. Hasinger, M. Brusa +13
We present the analysis of the source counts in the XMM-COSMOS survey using data of the first year of XMM-Newton observations. The survey covers ~2 deg^2 within the region of sky b…
