cds-question@unistra.frgalaxiesspectroscopyvisible-astronomysloan-photometryredshiftedThe Hubble Space Telescope Advanced Camera for Surveys grism Probing Evolution And Reionization Spectroscopically (PEARS) survey provides a large dataset of low-resolution spectra from thousands of galaxies in the GOODS north and south fields. One important subset of objects in these data is emission-line galaxies (ELGs), and we have investigated several different methods aimed at systematically selecting these galaxies. Here, we present a new methodology and results of a search for these ELGs in the PEARS observations of the Hubble Ultra Deep Field (HUDF) using a 2D detection method that utilizes the observation that many emission lines originate from clumpy knots within galaxies. This 2D line-finding method proves to be useful in detecting emission lines from compact knots within galaxies that might not otherwise be detected using more traditional 1D line-finding techniques.2008AJ....135.1624Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/135/1624CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/653/1004 : Galaxies at 1.4<~z<~3.0 in GOODS-North Field (Reddy+, 2006)J/ApJ/689/687 : GOODS-N spectroscopic survey (Barger+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/135/1624https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/135/1624http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/135/1624https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/135/1624https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/135/1624http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/135/1624GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/135/1624/table1 (Global properties of emission-line galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/135/1624/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/135/1624/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/135/1624/table1?GETtext/xml+votable180.050000true53.14339444-27.813453610.0055555555555555566/359352.5094373233074463e-19 2.655265855408273e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/135/1624?format=asciiOpticaldefaultJ/AJ/135/1624/table1Global properties of emission-line galaxiesLineLine ID (2)meta.id;spect.linecharrecnoRecord number assigned by the VizieR team.
