cds-question@unistra.frgalaxiesinfrared-sourcesmillimeter-astronomysubmillimeter-astronomyinterstellar-mediumWe present new Atacama Large Millimeter Array (ALMA) dust continuum observations of 101 log(M_*_/M_{sun}_)>9.5 galaxies in the COSMOS field to study the effect of the environment on the interstellar medium at z~0.7. At this redshift, our targets span a wide range of environments allowing for a diverse sample of galaxies with densities of {Sigma}=0.16-10.5Mpc^-2^ (per {Delta}z=0.024). Using the ALMA observations, we calculate the total interstellar medium (ISM) mass (M_ISM_) and look for depletion as a function of galaxy density in order to understand the quenching or triggering of star formation in galaxies in different environments. M_ISM_ is found to have a small dependence on the environment, while the depletion timescale remains constant (~200Myr) across all environments. We find elevated M_ISM_ values at intermediate densities and lower values at high densities compared to low (field) densities. Our observed evolution in gas fraction with density in this single redshift slice is equivalent to the observed evolution with cosmic time over 2-3Gyr. To explain the change in the gas mass fraction seen in galaxies in intermediate and high densities, these results suggest environmental processes such as mergers and ram pressure stripping are likely playing a role in dense filamentary cluster environments.2019ApJ...874...53Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/874/53CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/284 : COSMOS Multi-Wavelength Photometry Catalog (Capak+, 2007)VI/139 : Herschel Observation Log (Herschel Science Centre, 2013)J/A+A/327/522 : Molecular gas content of spiral galaxies (Boselli+ 1997)J/ApJS/172/70 : zCOSMOS-bright catalog, DR3 (Lilly+, 2007)J/A+A/532/A90 : PACS Evolutionary Probe (PEP-DR1) catalogs (Lutz+, 2011)J/A+A/533/A119 : GOODS-Herschel North and South catalogs (Elbaz+, 2011)J/ApJ/768/74 : PHIBSS: CO obs. of star-forming galaxies (Tacconi+, 2013)J/A+A/556/A55 : Multi-color phot. of star-forming galaxies (Ilbert+, 2013)J/A+A/557/A66 : Effective SEDs of IR galaxies at various z (Bethermin+, 2013)J/ApJ/775/78 : Lyman limit absorption systems in z~3 QSOs (Fumagalli+, 2013)J/ApJ/783/84 : ALMA obs. in 107 galaxies at z=0.2-2.5 (Scoville+, 2014)J/ApJS/221/11 : CANDELS visual classifications for GOODS-S (Kartaltepe+, 2015)J/ApJ/820/83 : ALMA galaxies in the COSMOS survey field (Scoville+, 2016)J/ApJS/224/24 : The COSMOS2015 catalog (Laigle+, 2016)J/ApJ/837/16 : Cosmic web of galaxies in the COSMOS field (Darvish+, 2017)J/A+A/608/A15 : ALMA survey of submm galaxies in COSMOS field (Brisbin+, 2017)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/874/53https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/874/53http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/874/53https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/874/53https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/874/53http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/874/53GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/874/53/table2 (properties and measurements)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/874/53/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/874/53/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/874/53/table2?GETtext/xml+votable180.050000true150.76950072.440000060.0055555555555555565/6814 6/27247https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/874/53?format=asciiInfraredMillimeterdefaultJ/ApJ/874/53/table2properties and measurementsSnu[0.26/1.2] Flux measurement, S_{nu}_mJyphot.flux.density;em.mm.200-400GHzfloate_Snu[0.1/0.2]?
