The Environments of Active Galactic Nuclei within the zCOSMOS Density Field
J. D. Silverman, K. Kovac, C. Knobel +58
The impact of environment on AGN activity up to z~1 is assessed by utilizing a mass-selected sample of galaxies from the 10k catalog of the zCOSMOS spectroscopic redshift survey. W…
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.…
The COSMOS AGN Spectroscopic Survey I: XMM Counterparts
Jonathan R. Trump, Chris D. Impey, Martin Elvis +17
We present optical spectroscopy for an X-ray and optical flux-limited sample of 677 XMM-Newton selected targets covering the 2 deg^2 COSMOS field, with a yield of 485 high-confiden…
Ongoing and co-evolving star formation in zCOSMOS galaxies hosting Active Galactic Nuclei
J. D. Silverman, F. Lamareille, C. Maier +60
We present a study of the host galaxies of AGN selected from the zCOSMOS survey to establish if accretion onto supermassive black holes and star formation are explicitly linked up…
The zCOSMOS redshift survey: the three-dimensional classification cube and bimodality in galaxy physical properties
M. Mignoli, G. Zamorani, M. Scodeggio +56
Aims. We investigate the relationships between three main optical galaxy observables (spectral properties, colours, and morphology), exploiting the data set provided by the COSMOS/…
Chasing highly obscured QSOs in the COSMOS field
F. Fiore, S. Puccetti, M. Brusa +41
(abridged) We take advantage of the deep Chandra and Spitzer coverage of a large area (more than 10 times the area covered by the Chandra deep fields, CDFs in the COSMOS field, to…
