cds-question@unistra.frgalaxiesspectroscopygalaxy-kinematicsredshiftedline-intensitiessurveysvisible-astronomyWe present the second data release of the Large Early Galaxy Astrophysics Census (LEGA-C), an ESO 130-night public spectroscopic survey conducted with VIMOS on the Very Large Telescope. We release 1988 spectra with typical continuum S/N~20{AA}^-1^ of galaxies at 0.6<~z<~1.0, each observed for ~20hr and fully reduced with a custom-built pipeline. We also release a catalog with spectroscopic redshifts, emission-line fluxes, Lick/IDS indices, and observed stellar and gas velocity dispersions that are spatially integrated quantities, including both rotational motions and genuine dispersion. To illustrate the new parameter space in the intermediate-redshift regime probed by LEGA-C, we explore relationships between dynamical and stellar population properties. The star-forming galaxies typically have observed stellar velocity dispersions of ~150km/s and strong H{delta} absorption (H{delta}_A_~5{AA}), while passive galaxies have higher observed stellar velocity dispersions (~200km/s) and weak H{delta} absorption (H{delta}_A_~0{AA}). Strong [OIII]5007/H{beta} ratios tend to occur mostly for galaxies with weak H{delta}_A_ or galaxies with higher observed velocity dispersion. Beyond these broad trends, we find a diversity of possible combinations of rest-frame colors, absorption-line strengths, and emission-line detections, illustrating the utility of spectroscopic measurements to more accurately understand galaxy evolution.2018ApJS..239...27Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/239/27CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/250 : The VIMOS VLT deep survey (VVDS-DEEP) (Le Fevre+ 2005)J/ApJS/234/21 : Hectospec survey of galaxies in COSMOS (Damjanov+, 2018)J/ApJ/830/51 : FourStar galaxy evolution survey (ZFOURGE) (Straatman+, 2016)J/ApJ/799/148 : DEIMOS galaxy sample at z~0.7 (Bezanson+, 2015)J/ApJ/795/165 : Line ratios in z~2-3 gal. from KBSS-MOSFIRE (Steidel+, 2014)J/ApJS/214/24 : 3D-HST+CANDELS catalog (Skelton+, 2014)J/MNRAS/442/533 : Recently quenched elliptical gal. in SDSS (McIntosh+, 2014)J/ApJ/788/72 : Observed sample of z~0.7 massive galaxies (Gallazzi+, 2014)J/ApJ/777/18 : Stellar mass functions of galaxies to z=4 (Muzzin+, 2013)J/ApJ/771/85 : Dynamical masses of z~2 quiescent gal.
