The Great Observatories Origins Deep Survey

<i>Context. <i/>We present the full data set of the VIsible Multi-Object Spectrograph (VIMOS) spectroscopic campaign of the ESO/GOODS program in the Chandra Deep Field South (CDFS), which complements the FORS2 ESO/GOODS spectroscopic campaign.<i>Aims. <i/>The ESO/GOODS spectroscopic programs are aimed at reaching signal-to-noise ratios adequate to measure redshifts for galaxies with AB magnitudes in the range ~24-25 in the <i>B<i/> and <i>R<i/> band using VIMOS, and in the <i>z<i/> band using FORS2.<i>Methods. <i/>The GOODS/VIMOS spectroscopic campaign is structured in two separate surveys using two different VIMOS grisms. The VIMOS Low Resolution Blue (LR-Blue) and Medium Resolution (MR) orange grisms have been used to cover different redshift ranges. The LR-Blue campaign is aimed at observing galaxies mainly at 1.8 < <i>z<i/> < 3.5, while the MR campaign mainly aims at galaxies at <i>z<i/> < 1 and Lyman Break Galaxies (LBGs) at <i>z<i/> > 3.5.<i>Results. <i/>The full GOODS/VIMOS spectroscopic campaign consists of 20 VIMOS masks. This release adds 8 new masks to the previous release (12 masks, Popesso et al. 2009, A&A, 494, 443). In total we obtained 5052 spectra, 3634 from the 10 LR-Blue masks and 1418 from the 10 MR masks. A significant fraction of the extracted spectra comes from serendipitously observed sources: ~21% in the LR-Blue and ~16% in the MR masks. We obtained 2242 redshifts in the LR-Blue campaign and 976 in the MR campaign for a total success rate of 62% and 69% respectively, which increases to 66% and 73% if only primary targets are considered. The typical redshift uncertainty is estimated to be 0.00084 (~255 km s<sup>-1<sup/>) for the LR-Blue grism and 0.00040 (~120 km s<sup>-1<sup/>) for the MR grism. By complementing our VIMOS spectroscopic catalog with all existing spectroscopic redshifts publicly available in the CDFS, we compiled a redshift master catalog with 7332 entries, which we used to investigate large scale structures out to <i>z<i/> 3.7. We produced stacked spectra of LBGs in a few bins of equivalent width (<i>EW<i/>) of the Ly-<i>α<i/> and found evidence for a lack of bright LBGs with high <i>EW<i/> of the Ly-<i>α<i/>. Finally, we obtained new redshifts for 12 X-ray sources of the CDFS and extended-CDFS.<i>Conclusions. <i/>After the completion of the two complementary ESO/GOODS spectroscopic campaigns with VIMOS and FORS2 at VLT, the number of spectroscopic redshifts in CDFS/GOODS field increased dramatically, in particular at <i>z<i/> 2. These data provide the redshift information indispensable to achieve the scientific goals of GOODS, such as tracing the evolution of galaxy masses, morphologies, clustering, and star formation.
