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 contains 1498 groups in total and 192 groups with more than five observed members. The catalog includes both group properties and the identification of the member galaxies. Based on mock catalogs, the completeness and purity of groups with three and more members should be both about 83% with respect to all groups that… Expand
Proto-groups at 1.8 < z < 3 in the zCOSMOS-deep Sample
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 this same redshift interval. TheseExpand
A group-galaxy cross-correlation function analysis in zCOSMOS
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 consistency test in theExpand
Dynamical analysis of strong-lensing galaxy groups at intermediate redshift
We present VLT spectroscopic observations of seven newly discovered galaxy groups between 0.3 < z < 0.7. The groups were selected from the Strong Lensing Legacy Survey (SL2S), a survey that consistsExpand

Colour Properties of Group Galaxies in Pan-STARRS MD Survey Fields
Abstract How environment shapes galaxies on groups scale in the early universe is poorly constrained. Here we carry out a study of the colour properties of galaxies against environment usingExpand

We report the results of a study which assembles deep observations with the ACIS-I instrument on the Chandra Observatory to study the evolution in the core properties of a sample of galaxy groups andExpand
The zCOSMOS redshift survey: evolution of the light in bulges and discs since z ~ 0.8
We studied the chronology of galactic bulge and disc formation by analysing the relative contributions of these components to the B-band rest-frame luminosity density at different epochs. We presentExpand
Efficient satellite quenching at z∼1 from the GEEC2 spectroscopic survey of galaxy groups
We present deep Gemini Multi-Object Spectrograph-South spectroscopy for 11 galaxy groups at 0.8 66 per cent) for eight of the 11 groups. Using an optical–near-infrared colour–colour diagram, theExpand
zCOSMOS 20k: satellite galaxies are the main drivers of environmental effects in the galaxy population at least to z ∼ 0.7
We explore the role of environment in the evolution of galaxies over 0.1 <z <0.7 using the final zCOSMOS-bright data set. Using the red fraction of galaxies as a proxy for the quenched population, weExpand
