Issue Date: | 2021 | Journal: | THE ASTROPHYSICAL JOURNAL SUPPLEMENT SERIES | Number: | 256 | Issue: | 2 | First Page: | 44 | Abstract: | We present the third and final data release of the Large Early Galaxy Astrophysics Census (LEGA-C), an ESO/Very Large Telescope public spectroscopic survey targeting 0.6 < z < 1.0, K<SUB>s</SUB>-selected galaxies. The data release contains 3528 spectra with measured stellar velocity dispersions and stellar population properties, a 25-fold increase in sample size compared to previous work. This K<SUB>s</SUB>-selected sample probes the galaxy population down to ~0.3L*, for all colors and morphological types. Along with the spectra, we publish a value-added catalog with stellar and ionized gas velocity dispersions, stellar absorption line indices, emission-line fluxes, and equivalent widths, complemented with structural parameters measured from Hubble Space Telescope Advanced Camera for Surveys imaging. With its combination of high precision and large sample size, LEGA-C provides a new benchmark for galaxy evolution studies. | URI: | http://hdl.handle.net/20.500.12386/31696 | URL: | https://iopscience.iop.org/article/10.3847/1538-4365/ac1356 https://api.elsevier.com/content/abstract/scopus_id/85117616691 |
