cds-question@unistra.frgalaxiesvisible-astronomysloan-photometryline-intensitiesTo derive a new H{alpha} luminosity function and to understand the clustering properties of star-forming galaxies at z~0.24, we have made a narrowband imaging survey for H{alpha}-emitting galaxies in the Hubble Space Telescope (HST) COSMOS 2 square degree field. We used the narrowband filter NB816 ({lambda}_c_=8150{AA}, {Delta}{lambda}=120{AA}) and sampled H{alpha} emitters with EW_obs_(H{alpha}+[NII])>12{AA} in a redshift range between z=0.233 and 0.251 corresponding to a depth of 70Mpc. We obtained 980 H{alpha}-emitting galaxies in a sky area of 5540arcmin^2^, corresponding to a survey volume of 3.1x10^4^Mpc^3^.2008ApJS..175..128Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/175/128CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/284 : COSMOS Multi-Wavelength Photometry Catalog (Capak+, 2007)J/ApJS/172/523 : COSMOS field Ly{alpha} emitters at z~5.7 (Murayama+, 2007)J/ApJS/172/456 : [OII] emitting galaxies in COSMOS + SDF fieldshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/175/128https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/175/128http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/175/128https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/175/128https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/175/128http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/175/128GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/175/128/table1 (A list of H{alpha} emitter candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/175/128/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/175/128/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/175/128/table1?GETtext/xml+votable180.050000true150.725331.61183390.0055555555555555565/6814 6/27245 27247 27344https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/175/128?format=asciiOpticaldefaultJ/ApJS/175/128/table1A list of H{alpha} emitter candidatesrecnoRecord number assigned by the VizieR team.
