The spatial clustering of X-ray selected AGN in the XMM-COSMOS field
R. Gilli, G. Zamorani, T. Miyaji +70
We study the spatial clustering of 538 X-ray selected AGN in the 2 deg^2 XMM-COSMOS field that are spectroscopically identified to I_{AB}<23 and span the redshift range z=0.2-3.0.…
High redshift quasars in the COSMOS survey: the space density of z>3 X-ray selected QSOs
M. Brusa, A. Comastri, R. Gilli +19
We present a new measurement of the space density of high redshift (3.0<z<4.5), X-ray selected QSOs obtained by exploiting the deep and uniform multiwavelength coverage of the COSM…
The XMM-Newton survey of the ELAIS-S1 field II: optical identifications and multiwavelength catalogue of X-ray sources
C. Feruglio, F. Fiore, F. La Franca +13
We present optical identifications and a multi-band catalogue of a sample of 478 X-ray sources in the XMM and Chandra surveys of the central 0.6 deg^2 of the ELAIS-S1 field. The op…
The Blast Wave Model for AGN Feedback: Effects on AGN Obscuration
N. Menci, F. Fiore, S. Puccetti +1
We compute the effect of the galactic absorption on AGN emission in a cosmological context by including a physical model for AGN feeding and feedback in a semi-analytic model of ga…
The candidate filament close to the 3C295 galaxy cluster: optical and X-ray spectroscopy
Valerio D'Elia, Fabrizio Fiore, Smita Mathur +1
We present a detailed analysis of the overdensity of X-ray sources colse to the 3C 295 galaxy cluster (z=0.46) to assess whether it is associated with a filament of the large-scale…
The prompt, high resolution spectroscopic view of the "naked-eye" GRB080319B
V. D'Elia, F. Fiore, R. Perna +21
GRB080319B reached 5th optical magnitude during the burst prompt emission. Thanks to the VLT/UVES rapid response mode, we observed its afterglow just 8m:30s after the GRB onset whe…
