Abstract:We use ALMA observations of CO(2-1) in 13 massive (M * ∼ > 10 11 M ) post-starburst galaxies at z ∼ 0.6 to constrain the molecular gas content in galaxies shortly after they quench their major star-forming episode. The post-starburst galaxies in this study are selected from the Sloan Digital Sky Survey spectroscopic samples (DR14) based on their spectral shapes, as part of the SQuIGG LE program. Early results showed that two post-starburst galaxies host large H 2 reservoirs despite their low inferred star form… Show more
