The Colors of Central and Satellite Galaxies in zCOSMOS out to z ~ 0.8 and Implications for Quenching
C. Knobel, S. J. Lilly, K. Kovac +47
We examine the red fraction of central and satellite galaxies in the large zCOSMOS group catalog out to z ~ 0.8 correcting for both the incompleteness in stellar mass and for the l…
Proto-groups at 1.8<z<3 in the zCOSMOS-deep sample
C. Diener, S. J. Lilly, C. Knobel +48
We identify 42 candidate groups lying between 1.8<z<3.0 from a sample of 3502 galaxies with spectroscopic redshifts in the zCOSMOS-deep redshift survey within the same redshift int…
The cosmic evolution of oxygen and nitrogen abundances in star-forming galaxies over the past 10 Gyrs
E. Perez-Montero, T. Contini, F. Lamareille +35
The chemical evolution of galaxies on a cosmological timescale is still a matter of debate despite the increasing number of available data provided by spectroscopic surveys of star…
GMASS ultradeep spectroscopy of galaxies at z~2 - VII. Sample selection and spectroscopy
Jaron Kurk, Andrea Cimatti, Emanuele Daddi +12
The populations of both quiescent and actively star-forming galaxies at 1<z<2 are still under-represented in our spectroscopic census of galaxies throughout the history of the Univ…
The VIMOS Public Extragalactic Redshift Survey (VIPERS): spectral classification through Principal Component Analysis
A. Marchetti, B. R. Granett, L. Guzzo +51
We develop a Principal Component Analysis aimed at classifying a sub-set of 27,350 spectra of galaxies in the range 0.4 < z < 1.0 collected by the VIMOS Public Extragalactic Redshi…
A group-galaxy cross-correlation function analysis in zCOSMOS
C. Knobel, S. J. Lilly, C. M. Carollo +46
We present a group-galaxy cross-correlation analysis using a group catalog produced from the 16,500 spectra from the optical zCOSMOS galaxy survey. Our aim is to perform a consiste…
The zCOSMOS 20k Group Catalog
C. Knobel, S. J. Lilly, A. Iovino +48
We present an optical group catalog between 0.1 < z < 1 based on 16,500 high-quality spectroscopic redshifts in the completed zCOSMOS-bright survey. The catalog published herein co…
Environmental effects in the interaction and merging of galaxies in zCOSMOS survey
P. Kampczyk, S. J. Lilly, the zCOSMOS Collaboration
The zCOSMOS-bright 10k spectroscopic sample reveals a strong environmental dependence of close kinematic galaxy pair fractions in the redshift range 0.2 < z < 1. The fraction of cl…
Bolometric luminosities and Eddington ratios of X-ray selected Active Galactic Nuclei in the XMM-COSMOS survey
E. Lusso, A. Comastri, B. D. Simmons +25
Bolometric luminosities and Eddington ratios of both X-ray selected broad-line (Type-1) and narrow-line (Type-2) AGN from the XMM-Newton survey in the COSMOS field are presented. T…
The COSMOS Density Field: A Reconstruction Using Both Weak Lensing and Galaxy Distributions
A. Amara, S. Lilly, K. Kovac +49
The COSMOS field has been the subject of a wide range of observations, with a number of studies focusing on reconstructing the 3D dark matter density field. Typically, these studie…
Comparison of the VIMOS-VLT Deep Survey with the Munich semi-analytical model. II. The colour-density relation up to z=1.5
O. Cucciati, G. De Lucia, E. Zucca +10
[Abridged] We perform on galaxy mock catalogues the same colour-density analysis made by Cucciati et al. (2006) on a 5 Mpc/h scale using the VVDS-Deep survey, and compare the resul…
The dominant role of mergers in the size evolution of massive early-type galaxies since z ~ 1
C. López-Sanjuan, O. Le Fèvre, O. Ilbert +60
In this paper we measure the merger fraction and rate, both minor and major, of massive early-type galaxies (M_star >= 10^11 M_Sun) in the COSMOS field, and study their role in mas…
The power spectrum from the angular distribution of galaxies in the CFHTLS-Wide fields at redshift ~0.7
B. R. Granett, L. Guzzo, J. Coupon +32
We measure the real-space galaxy power spectrum on large scales at redshifts 0.5 to 1.2 using optical colour-selected samples from the CFHT Legacy Survey. With the redshift distrib…
A journey from the outskirts to the cores of groups I: Color- and mass-segregation in 20K-zCOSMOS groups
V. Presotto, A. Iovino, M. Scodeggio +49
Using the group catalog obtained from zCOSMOS spectroscopic data and the complementary photometric data from the COSMOS survey, we explore segregation effects occurring in groups o…
Improved constraints on the expansion rate of the Universe up to z~1.1 from the spectroscopic evolution of cosmic chronometers
M. Moresco, A. Cimatti, Raul Jimenez +65
We present new improved constraints on the Hubble parameter H(z) in the redshift range 0.15 < z < 1.1, obtained from the differential spectroscopic evolution of early-type galaxies…
Accuracy of photometric redshifts for future weak lensing surveys from space
Fabio Bellagamba, Massimo Meneghetti, Lauro Moscardini +1
Photometric redshifts are a key tool to extract as much information as possible from planned cosmic shear experiments. In this work we aim to test the performances that can be achi…
