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.…

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/…

The close environment of 24 micron galaxies at 0.6<z<1.0 in the COSMOS field

K. I. Caputi, K. Kovac, M. Bolzonella +62

We investigate the close environment of 203 Spitzer 24 micron-selected sources at 0.6<z<1.0 using zCOSMOS-bright redshifts and spectra of I<22.5 AB mag galaxies, over 1.5 sq. deg.…

COSMOS Photometric Redshifts with 30-bands for 2-deg2

O. Ilbert, P. Capak, M. Salvato +60

We present accurate photometric redshifts in the 2-deg2 COSMOS field. The redshifts are computed with 30 broad, intermediate, and narrow bands covering the UV (GALEX), Visible-NIR…

The optical spectra of 24 micron galaxies in the COSMOS field: I. Spitzer/MIPS bright sources in the zCOSMOS-bright 10k catalogue

K. I. Caputi, S. J. Lilly, H. Aussel +23

We study zCOSMOS-bright optical spectra for 609 Spitzer/MIPS 24 micron-selected galaxies with S(24um)> 0.30 mJy and I<22.5 (AB mag) over 1.5 sq. deg. of the COSMOS field. From emis…

Clustering of Lyman alpha emitters at z ~ 4.5

Katarina Kovač, Rachel S. Somerville, James E. Rhoads +2

We present the clustering properties of 151 Lyman alpha emitting galaxies at z ~ 4.5 selected from the Large Area Lyman Alpha (LALA) survey. Our catalog covers an area of 36' x 36'…

Large scale structure in the HI Parkes All-Sky Survey: Filling the Voids with HI galaxies?

S. Basilakos, M. Plionis, K. Kovac +1

We estimate the two-point correlation function in redshift space of the recently compiled HIPASS neutral hydrogen (HI) sources catalogue, which if modeled as a power law, $ξ(r)=(r_…

zCOSMOS: A Large VLT/VIMOS redshift survey covering 0 < z < 3 in the COSMOS field

S. J. Lilly, O. Le Fevre, A. Renzini +42

zCOSMOS is a large redshift survey that is being undertaken in the COSMOS field using 600 hours of observation with the VIMOS spectrograph on the 8-m VLT. The survey is designed to…

Large Scale structure in the HI Parkes ALL-Sky Survey (HIPASS)

S. Basilakos, K. Kovac, M. Aragon +2

We study the clustering properties of the recently compiled HIPASS neutral hydrogen (HI) sources catalogue using the two point correlation function in redshift space. If the two po…

The Faint End of the HI Mass Function

K. Kovac, T. A. Oosterloo, J. M. van der Hulst

We study the faint end of the HI mass function (HIMF) in order to test the predictions of the CDM theory on the number density of objects with small (dark) masses. The neutral hydr…
