cds-question@unistra.frsurveysultraviolet-astronomygalaxiesphotometrygalaxy-classification-systemsWe present the final data release from the GALEX Arecibo SDSS Survey (GASS), a large Arecibo programme that measured the HI properties for an unbiased sample of ~800 galaxies with stellar masses greater than 10^10^M_{sun}_ and redshifts 0.025<z<0.05. This release includes new Arecibo observations for 250 galaxies. We use the full GASS sample to investigate environmental effects on the cold gas content of massive galaxies at fixed stellar mass. The environment is characterized in terms of dark matter halo mass, obtained by cross-matching our sample with the Sloan Digital Sky Survey (SDSS) group catalogue of Yang et al. Our analysis provides, for the first time, clear statistical evidence that massive galaxies located in haloes with masses of 10^13^-10^14^M_{sun}_ have at least 0.4dex less HI than objects in lower density environments. The process responsible for the suppression of gas in group galaxies most likely drives the observed quenching of the star formation in these systems. Our findings strongly support the importance of the group environment for galaxy evolution, and have profound implications for semi-analytic models of galaxy formation, which currently do not allow for stripping of the cold interstellar medium in galaxy groups.2013MNRAS.436...34Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/436/34CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/403/683 : GALEX Arecibo SDSS survey (GASS) (Catinella+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/436/34https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/436/34http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/436/34https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/436/34https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/436/34http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/436/34GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/436/34/tablea1 (SDSS and UV parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/436/34/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/436/34/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/436/34/tablea1?GETtext/xml+votable180.050000true0.503416715.02558330.0055555555555555566/523-524 526-527 545 547 550 552 556 4107 4155 4168-4169 4182 4185 4193-4194 4298 4301 4329 4410 4591 4650 4652 4684 4708 4772 4789 4849 4866 4934 4946 4952 4959 4990 4993 5121 5158 5180 5215 5221 5295 5305 5639 5657 6161 6243-6244 6438 8208 8225 8230 8232 8245-8246 8269 8271 8288 8296-8297 8323-8324 8333 8338 8344 8351 8378 8392 8699-8700 8702 8714 8918 8927 8938-8939 9072 9111 9117-9118 9128 10261 10297-10298 10339 10342 10348 10397 10400-10401 10403 10538 18295 18300-18301 18303 18383 18388 18396 18405-18406 18411-18412 18417 19325 19432 19671 19678 19686 19696-19697 19732 19734 19742 19753 19778 19841 19983 19985-19986 19992-19993 19996 19998 20005 20007 20013 20017 22364 22399 25979 25981 26054 26058 26065 26088 26090 26092 26104 26235 26238 26349 26534 26540 26544-26545 26548 26606 27001 27071 27084 27090 27096 27127 27135 27364 27401 27413 27435 27458 27474 27480-27481 27483 27501 27509-27510 27566-27567 27586-27587 27589 27591 27595 27598 27602 27617 27709 27719 27730 27754-27755 27793 27807 27827-27828 27831 27834 27836 27841 28154 28158 28163 28403 28406-28407 28409 28414 28496 28554 28564 28571 28608-28609 31405 31657-31658https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/436/34?format=asciiUVOpticaldefaultJ/MNRAS/436/34/tablea1SDSS and UV parametersrecnoRecord number assigned by the VizieR team.
