Abstract
We present a homogeneous and complete catalogue of optical galaxy groups identified in the VIMOS-VLT spectroscopic Deep Survey (VVDS). We use mock catalogues extracted from the Millennium simulation to study the potential systematics that might affect the overall distribution of the identified systems. We train on these mock catalogues the adopted group-finding technique (the Voronoi-Delaunay Method, VDM), to recover in an unbiased way the redshift and velocity dispersion distributions of groups and maximise the level of completeness (C) and purity (P) of the group catalogue. We identify 318(/144) VVDS groups with at least 2(/3) members within 0. 2 ≤ z ≤ 1. 0, globally with C = 60% and P = 50%. We use the group sample to study the redshift evolution of the fraction f b of blue galaxies within 0. 2 ≤ z ≤ 1 in both groups and in the total VVDS galaxy sample.
