Laura Pentericci (INAF-OAR), "The VANDELS ESO public spectroscopic survey: highlights and future prospects"
VANDELS was a uniquely deep spectroscopic survey of high-redshift galaxies in the CANDELS UDS and CDFS fields with the VIMOS spectrograph on the VLT. Using integration times of 20-80 hours, the fundamental aim of the survey was to provide the high-signal-to-noise ratio spectra necessary to measure key physical properties such as stellar population ages, masses, metallicities, and outflow velocities from detailed absorption-line studies. The final VANDELS data release (DR4) features spectra and redshift measurements for 2087 galaxies, preselected to belong to three main target categories: (a) bright star-forming galaxies at 2.4 < z < 5.5, (b) massive quiescent galaxies at 1.0 < z < 2.5, and (c) fainter star-forming galaxies at 3.0 < z < 7.0. In this talk, I will present an overview of the survey and review the most important science results obtained by the VANDELS team.
