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…
Q2237+0305 in X-rays: spectra and variability with XMM-Newton
E. V. Fedorova, V. I. Zhdanov, C. Vignali +1
X-ray observations of gravitationally lensed quasars may allow us to probe the inner structure of the central engine of a quasar. Observations of Q2237+0305 (Einstein Cross) in X-r…
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…
On the peculiar properties of the narrow-line quasar PG 1543+489
C. Vignali, E. Piconcelli, S. Bianchi +1
We present the analysis of four XMM-Newton observations of the narrow-line quasar PG 1543+489 at z=0.400 carried out over a rest-frame time-scale of about three years. The X-ray sp…
Science with Simbol-X
F. Fiore, M. Arnaud, U. Briel +20
Simbol-X is a French-Italian mission, with a participation of German laboratories, for X-ray astronomy in the wide 0.5-80 keV band. Taking advantage of emerging technology in mirro…
