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 <…
MASSIV: Mass Assembly Survey with SINFONI in VVDS. III. Evidence for positive metallicity gradients in z~1.2 star-forming galaxies
J. Queyrel, T. Contini, M. Kissler-Patig +11
A key open issue for galaxy evolution and formation models is the understanding of the different mechanisms of galaxy assembly at various cosmic epochs. The aim of this study is to…
MASSIV: Mass Assemby Survey with SINFONI in VVDS. I. Survey description and global properties of the 0.9 < z < 1.8 galaxy sample
T. Contini, B. Garilli, O. Le Fevre +11
Understanding how galaxies evolve and assemble their mass across cosmic time is still a fundamental unsolved issue. To get insight into the various processes of galaxy mass assembl…
Euclid Definition Study Report
R. Laureijs, J. Amiaux, S. Arduini +216
Euclid is a space-based survey mission from the European Space Agency designed to understand the origin of the Universe's accelerating expansion. It will use cosmological probes to…
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…
Galaxy cluster searches based on photometric redshifts in the four CFHTLS Wide fields
F. Durret, C. Adami, A. Cappi +19
We have developed a method for detecting clusters in large imaging surveys, based on the detection of structures in galaxy density maps made in slices of photometric redshifts. Thi…
