Abstract

The Large Early Galaxy Astrophysics Census (LEGA-C) survey is the final Public Spectroscopic Survey to be completed with the now-retired VIsible Multi-Object Spectrograph (VIMOS) instrument at ESO’s Very Large Telescope (VLT). Its aim is to characterise with high precision and for a very large sample the stellar population and kinematic properties of galaxies at redshifts 0.6 < z < 1, providing a first assessment of the star formation histories, the absolute mass scale, and the stellar kinematic structure of galaxies at large lookback times (7 gigayears ago). This article coincides with the third and final data release but mostly focuses on the large variety of scientific results achieved so far.
