cds-question@unistra.frgalaxiesphotometrysurveysWe present a rest-frame ultraviolet analysis of ~120 z~3.1 Lyman Alpha Emitters (LAEs) in the Extended Chandra Deep Field South. Using Hubble Space Telescope (HST) images taken as part of the Galaxy Evolution From Morphology and SEDS (GEMS) survey, Great Observatories Origins Deep Survey (GOODS), and Hubble Ultradeep Field surveys, we analyze the sizes of LAEs, as well as the spatial distribution of their components, which are defined as distinct clumps of UV-continuum emission. We set an upper limit of ~1kpc (~0.1") on the rms offset between the centroids of the continuum and Ly{alpha} emission. Most of the multi-component LAEs identified in shallow frames become connected in deeper images, suggesting that the majority of the rest-UV "clumps" are individual star-forming regions within a single system.2009ApJ...705..639Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/705/639CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/261 : GOODS initial results (Giavalisco+, 2004)J/A+A/498/13 : Lyman-{alpha} emitters from redshifts z~2-3 (Nilsson+, 2009)J/ApJS/172/615 : GALFIT result for GEMS galaxies (Haussler+, 2007)J/ApJ/667/79 : Ly{alpha} emission-line galaxies at z=3.1 (Gronwall+, 2007)J/AJ/132/1729 : Hubble Ultra Deep Field BVI-dropout sources (Beckwith+, 2006)J/PASJ/57/165 : Ly{alpha} emitters in the SUBARU Deep Field (Taniguchi+, 2005)J/PASJ/57/881 : Imaging of high-redshift Lyman alpha emitters (Yamada+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/705/639https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/705/639http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/705/639https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/705/639https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/705/639http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/705/639GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/705/639/table2 (LAE photometric properties in GEMS (Galaxy Evolution from Morphology and SEDs))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/705/639/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/705/639/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/705/639/table2?GETtext/xml+votable180.050000true53.1699375-27.768343610.005555555555555556Cone search capability for table J/ApJ/705/639/table3 (LAE component photometric properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/705/639/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/705/639/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/705/639/table3?GETtext/xml+votable180.050000true53.1699375-27.768343610.0055555555555555566/35935 35957https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/705/639?format=asciiOpticaldefaultJ/ApJ/705/639/table2LAE photometric properties in GEMS (Galaxy Evolution from Morphology and SEDs)recnoRecord number assigned by the VizieR team.
