PEARS covers fields within both the Great Observatories Origins Deep Survey (GOODS) North and South fields, making it ideal as a random survey of galaxies, as well as the availability of a wide variety of ancillary observations complemented by the spectroscopic results. Using the PEARS data, we are able to identify star-forming galaxies (SFGs) within the redshift volume 0<z<1.5. Star-forming regions in the PEARS survey are pinpointed independently of the host galaxy. This method allows us to detect the presence of multiple emission-line regions (ELRs) within a single galaxy. We identified a total of 1162 H{alpha}, [OIII], and/or [OII] emission lines in the PEARS sample of 906 galaxies to a limiting flux of ~10^-18^erg/s/cm2. The ELRs have also been compared to the properties of the host galaxy, including morphology, luminosity, and mass. From this analysis, we find three key results: (1) the computed line luminosities show evidence of a flattening in the luminosity function with increasing redshift; (2) the star-forming systems show evidence of complex morphologies with star formation occurring predominantly within one effective (half-light) radius. However, the morphologies show no correlation with host stellar mass. (3) Also, the number density of SFGs with M_*_>=10^9^M_{sun}_ decreases by an order of magnitude at z<=0.5 relative to the number at 0.5<z<0.9, supporting the argument of galaxy downsizing.2013ApJ...772...48Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/772/48CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/261 : GOODS initial results (Giavalisco+, 2004)J/AJ/141/64 : PEARS emission-line galaxies spectroscopy (Xia+, 2011)J/AJ/141/14 : HST WFC3 ERS : emission-line galaxies (Straughn+, 2011)J/ApJ/742/111 : Extreme emission-line gal. in CANDELS (van der Wel+, 2011)J/ApJ/706/158 : Early-type galaxies in PEARS (Ferreras+, 2009)J/ApJ/695/1591 : Spectrophotometry in PEARS fields (Pirzkal+, 2009)J/AJ/138/1022 : Emission-line galaxies from HST PEARS survey (Straughn+, 2009)J/AJ/135/1624 : PEARS emission-line galaxies (Straughn+, 2008)J/ApJS/172/456 : [OII] emitting gal. in COSMOS + SDF fields (Takahashi+, 2007)J/ApJ/659/162 : CAS parameters of 199 nearby galaxies (Taylor-Mager+, 2007)J/ApJ/657/738 : SDF galaxies multi-photometry (Ly+, 2007)J/ApJ/633/871 : Positions and photometry of HII knots in M51 (Calzetti+, 2005)J/AJ/130/1324 : Faint emission-line galaxies at z<=1.6 (Drozdovsky+, 2005)J/AJ/128/163 : Galaxy morphological classification (Lotz+, 2004)J/AJ/126/539 : The Chandra Deep Fields North and South (Alexander+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/772/48https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/772/48http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/772/48https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/772/48https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/772/48http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/772/48GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/772/48/table2 (Properties of 883 PEARS emission-line galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/772/48/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/772/48/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/772/48/table2?GETtext/xml+votable180.050000true189.1859230662.16982750.0055555555555555566/11252 359352.0401237512456292e-19 2.706461185444514e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/772/48?format=asciiOpticalInfrareddefaultJ/ApJ/772/48/table2Properties of 883 PEARS emission-line galaxiesrecnoRecord number assigned by the VizieR team.
