We select EELGs on the basis of substantial excess flux in the z broad band, which is sensitive to H{alpha} at 0.3<~z<~0.42 and [OIII]{lambda}5007 at 0.7<~z<~0.86. We identify 10470 galaxies with zexcesses in the COSMOS data set and 91385 in the NEP field. We cross- reference the COSMOS EELG sample with the zCOSMOS and DEIMOS 10k spectral catalogs, finding 1395 spectroscopic matches. We made an additional 71 (46 unique) spectroscopic measurements with Y<23 using the HYDRA multiobject spectrograph on the WIYN 3.5m telescope, and 204 spectroscopic measurements from the DEIMOS spectrograph on the Keck II telescope, providing a total of 1441/10470 spectroscopic redshifts for the EELG sample in COSMOS (~14%). We confirm that 1418 (~98%) are H{alpha} or [OIII]{lambda}5007 emitters in the above stated redshift ranges. We also identify 240 redshifted H{alpha} and [OIII]{lambda}5007 emitters in the NEP using spectra taken with WIYN/HYDRA and Keck/DEIMOS. Using broadband-selection techniques in the g-r-i color space, we distinguish between H{alpha} and [OIII]{lambda}5007 emitters with 98.6% accuracy. We test our EELG selection by constructing H{alpha} and [OIII]{lambda}5007 luminosity functions and comparing to recent literature results. We conclude that broadband magnitudes from HSC, the Vera C. Rubin Observatory, and other deep optical multiband surveys can be used to select EELGs in a straightforward manner.2022ApJ...928...78Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/928/78CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/292 : DESI Legacy Imaging Surveys DR8 photometric redshifts (Duncan, 2022)J/ApJ/668/853 : Spectroscopy of UltraStrong Em.
