Abstract: The VANDELS survey used the VIMOS spectrograph on ESO’s VLT to obtain ultra-deep, medium resolution, optical spectra of galaxies within the UKIDSS Ultra Deep Survey (UDS) and Chandra Deep Field South (CDFS) survey fields (0.2 sq. degree total area). Using robust photometric redshift pre-selection, VANDELS targeted ~2100 galaxies in the redshift interval 1.0 < z < 7.0, with 85% of its targets selected to be at a redshift greater than 3. In addition, VANDELS targeted a substantial number of passive galaxies in the redshift interval 1.0 < z < 2.5. Exploiting the red sensitivity of the refurbished VIMOS spectrograph, the survey obtained ultra-deep optical spectroscopy with the VIMOS MR grism and GG475 order-sorting filter, which covers the wavelength range 4800-10000Å at a dispersion of 2.5 Å/pix and a spectral resolution of R~600. Each galaxy received between a minimum of 20-hours and a maximum of 80-hours of on-source integration time. The fundamental aim of the survey was to provide the high signal-to-noise spectra necessary to measure key physical properties such as stellar population ages, metallicities and outflow velocities from detailed absorption-line studies. By targeting two extra-galactic survey fields with superb multi-wavelength imaging data, VANDELS was designed to produce a unique legacy dataset for exploring the physics underpinning high-redshift galaxy evolution.
Other: This is a dynamic dataset; it is growing as new data is added. The DOI refers to the newest available dataset.
