cds-question@unistra.frline-intensitiesextinctioninfrared-photometrygalaxiesinfrared-sourcesWe present the results of an H{alpha} near-infrared narrowband survey searching for star-forming galaxies at redshift z=0.84. This work is an extension of our previous narrowband studies in the optical at lower redshifts. After removal of stars and redshift interlopers (using spectroscopic and photometric redshifts), we build a complete sample of 165 H{alpha} emitters in the extended Groth strip and GOODS-N fields with L(H{alpha})>10^41^ergs/s. We compute the H{alpha} luminosity function at z=0.84 after corrections for [NII] flux contamination, extinction, systematic errors, and incompleteness. Our sources present an average dust extinction of A(H{alpha})=1.5mag. Adopting H{alpha} as a surrogate for the instantaneous SFR, we measure an extinction-corrected SFR density of 0.17^+0.03^_-0.03_M_{sun}_/yr/Mpc^3^. Combining this result to our prior measurements at z=0.02, 0.24, and 0.40, we derive an H{alpha}-based evolution of the SFR density proportional to (1+z)^{beta}^ with {beta}=3.8+/-0.5. This evolution is consistent with that derived by other authors using different SFR tracers.2008ApJ...677..169Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/677/169CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/95/387 : Universidad Complutense de Madrid list 1 (Zamorano+ 1994)J/ApJS/105/343 : Universidad Complutense de Madrid list 2 (Zamorano+ 1996)J/A+A/379/798 : ELAIS H{alpha} emitting galaxies (Pascual+, 2001)J/ApJS/177/431 : Mid-IR sources in EGS (Barmby+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/677/169https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/677/169http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/677/169https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/677/169https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/677/169http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/677/169GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/677/169/table2 (Observed sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/677/169/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/677/169/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/677/169/table2?GETtext/xml+votable180.050000true214.3987252.360670.0055555555555555566/11249 11252 11424 11425https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/677/169?format=asciiInfrareddefaultJ/ApJ/677/169/table2Observed samplerecnoRecord number assigned by the VizieR team.
