The VIMOS-VLT deep survey. Color bimodality and the mix of galaxy populations up to z ~ 2

Résumé

Aims: In this paper we discuss the mix of star-forming and passive galaxies up to z ~ 2, based on the first epoch VIMOS-VLT Deep Survey (VVDS) data.
Methods: We compute rest-frame magnitudes and colors and analyse the color-magnitude relation and the color distributions. We also use the multi-band VVDS photometric data and spectral templates fitting to derive multi-color galaxy types. Using our spectroscopic dataset we separate galaxies based on a star-formation activity indicator derived combining the equivalent width of the [OII] emission line and the strength of the D_n(4000) continuum break.
Results: In agreement with previous works we find that the global galaxy rest-frame color distribution follows a bimodal distribution at z
