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…
Photometric redshift and classification for the XMM-COSMOS sources
M. Salvato, G. Hasinger, O. Ilbert +40
We present photometric redshifts and spectral energy distribution (SED) classifications for a sample of 1542 optically identified sources detected with XMM in the COSMOS field. Our…
XMM-Newton observations of the Lockman Hole: X-ray source catalogue and number counts
H. Brunner, N. Cappelluti, G. Hasinger +4
The Lockman Hole field represents the sky area of lowest Galactic line-of-sight column density N_H=5.7X10^19 cm^-2. It was observed by the XMM-Newton X-ray observatory in 18 pointi…
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…
The 3D soft X-ray cluster-AGN cross-correlation function in the ROSAT NEP survey
N. Cappelluti, H. Boehringer, P. Schuecker +4
X-ray surveys facilitate investigations of the environment of AGNs. Deep Chandra observations revealed that the AGNs source surface density rises near clusters of galaxies. The nat…
