VizieR Online Data Catalog: xGASS catalog (Catinella+, 2018)

We presented xGASS, the culmination of several years of effort to gather deep HI observations for a stellar mass-selected sample of ~1200 galaxies with homogeneously measured optical and SF properties. xGASS is the combination of the original GASS survey, which started in 2008 and targeted galaxies with stellar masses larger than 10¹⁰M_ȯ, and its extension to M*=10⁹M_ȯ. Together, these surveys required ~1300h of Arecibo telescope time. Our unique approach of carrying out gas fraction-limited observations down to MHI/M*~2 per cent allowed us to obtain stringent upper limits, which are essential to interpret variations of gas content as a function of galaxy properties.
