Environmental effects in the interaction and merging of galaxies in zCOSMOS
P. Kampczyk, S. J. Lilly, L. de Ravel +56
(Abridged) We analyze the environments and galactic properties (morphologies and star-formation histories) of a sample of 153 close kinematic pairs in the redshift range 0.2 < z <…
X-ray Groups of Galaxies at 0.5<z<1 in zCOSMOS: Increased AGN Activities in High Redshift Groups
M. Tanaka, A. Finoguenov, S. J. Lilly +48
We present a photometric and spectroscopic study of galaxies at 0.5<z<1 as a function of environment based on data from the zCOSMOS survey. There is a fair amount of evidence that…
The impact of galaxy interactions on AGN activity in zCOSMOS
J. D. Silverman, P. Kampczyk, K. Jahnke +52
Close encounters between galaxies are expected to be a viable mechanism, as predicted by numerical simulations, by which accretion onto supermassive black holes can be initiated. T…
Dissecting Photometric redshift for Active Galactic Nuclei using XMM- and Chandra-COSMOS samples
M. Salvato, O. Ilbert, G. Hasinger +61
With this paper, we release accurate photometric redshifts for 1692 counterparts to Chandra sources in the central square degree of the COSMOS field. The availability of a large tr…
The evolution of quiescent galaxies at high redshift (z > 1.4)
H. Domínguez Sánchez, F. Pozzi, C. Gruppioni +45
We have studied the evolution of high redshift quiescent galaxies over an effective area of ~1.7 deg^2 in the COSMOS field. Galaxies have been divided according to their star-forma…
The radial and azimuthal profiles of Mg II absorption around 0.5 < z < 0.9 zCOSMOS galaxies of different colors, masses and environments
R. Bordoloi, S. J. Lilly, C. Knobel +50
We map the radial and azimuthal distribution of Mg II gas within 200 kpc (physical) of 4000 galaxies at redshifts 0.5 < z < 0.9 using co-added spectra of more than 5000 background…
Black hole accretion and host galaxies of obscured quasars in XMM-COSMOS
V. Mainieri, A. Bongiorno, A. Merloni +61
We explore the connection between black hole growth at the center of obscured quasars selected from the XMM-COSMOS survey and the physical properties of their host galaxies. We stu…
The zCOSMOS redshift survey : Influence of luminosity, mass and environment on the galaxy merger rate
L. de Ravel, P. Kampczyk, O. Le Fèvre +56
The contribution of major mergers to galaxy mass assembly along cosmic time is an important ingredient to the galaxy evolution scenario. We aim to measure the evolution of the merg…
The Void Galaxy Survey
R. van de Weygaert, K. Kreckel, E. Platen +9
The Void Galaxy Survey (VGS) is a multi-wavelength program to study 60 void galaxies. Each has been selected from the deepest interior regions of identified voids in the SDSS…
