cds-question@unistra.frsurveysgalaxiescatalogsphotometryspectroscopyWe estimate the number counts of line emitters at high redshift and their evolution with cosmic time based on a combination of photometry and spectroscopy. We predict the H{alpha}, H{beta}, [OII], and [OIII] line fluxes for more than 35000 galaxies down to stellar masses of ~10^9^M_{sun}_ in the COSMOS and GOODS-S fields, applying standard conversions and exploiting the spectroscopic coverage of the FMOS-COSMOS survey at z~1.55 to calibrate the predictions. We calculate the number counts of H{alpha}, [OII], and [OIII] emitters down to fluxes of 1x10^-17^erg/cm^2^/s in the range 1.4<z<1.8 covered by the FMOS-COSMOS survey. We model the time evolution of the differential and cumulative H{alpha} counts, steeply declining at the brightest fluxes. We expect ~9300-9700 and ~2300-2900-galaxies/deg^2^ for fluxes >=1x10^-16^ and >=2x10^-16^erg/cm^2^/s over the range of 0.9<z<1.8. We show that the observed evolution of the main sequence of galaxies with redshift is enough to reproduce the observed counts variation at 0.2<z<2.5. We characterize the physical properties of the H{alpha} emitters with fluxes >=2x10^-16^erg/cm^2^/s including their stellar masses, UV sizes, [NII]/H{alpha} ratios and H{alpha} equivalent widths. An aperture of R~R_e_~0.5arcsec maximizes the signal-to-noise ratio for a detection, whilst causing a factor of ~2x flux losses, influencing the recoverable number counts, if neglected. Our approach, based on deep and large photometric data sets, reduces the uncertainties on the number counts due to the selection and spectroscopic samplings whilst exploring low fluxes. We publicly release the line flux predictions for the explored photometric samples.2017MNRAS.472.4878Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/472/4878CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/220/12 : FMOS-COSMOS survey III. 0.7<z<2.5 galaxies (Silverman+, 2015)J/ApJS/224/24 : The COSMOS2015 catalog (Laigle+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/472/4878https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/472/4878http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/472/4878https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/472/4878https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/472/4878http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/472/4878GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/472/4878/cosmos (Photometric parameters and line flux predictions for 31193 galaxies in COSMOS at 1.4<z<1.8)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/472/4878/cosmos?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/472/4878/cosmos?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/472/4878/cosmos?GETtext/xml+votable180.050000true150.322351.61483180.005555555555555556Cone search capability for table J/MNRAS/472/4878/goodss (Photometric parameters and line flux predictions for 3858 galaxies in GOODS-S at 1.4<z<1.8)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/472/4878/goodss?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/472/4878/goodss?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/472/4878/goodss?GETtext/xml+votable180.050000true53.084888-27.9558130.0055555555555555565/6814 6/27245 27247 27344 35935https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/472/4878?format=asciidefaultJ/MNRAS/472/4878/cosmosPhotometric parameters and line flux predictions for 31193 galaxies in COSMOS at 1.4<z<1.8recnoRecord number assigned by the VizieR team.
