Keck Sample of Quiescent Galaxies

This dataset comprises 167 Keck spectra of high-redshift galaxies. The primary targets are massive quiescent galaxies, but low-mass and/or star-forming objects are also present. The sample was obtained with the main goal of studying the rest-frame optical stellar continuum; the main features that were targeted are the Balmer absorption lines, CaII H and K, 4000A break, G band, and also the [OII] emission line. However, the exact rest-frame wavelength range is different for each object, depending on redshift and position on the slitmask. Each of the 167 spectra yielded a spectroscopic redshift measurement via absorption and/or emission lines; more galaxies were targeted during the observations but no identifiable features could be detected in their spectra.
