cds-question@unistra.frgalaxiesspectroscopyredshiftedline-intensitiessurveysWe present a large sample of Ly{alpha}-emitting galaxies (LAEs) spectroscopically confirmed at redshift z~4.5, based on Inamori-Magellan Areal Camera and Spectrograph spectroscopic observations of candidate z~4.5 Ly{alpha}-emitting galaxies in the large area Lyman alpha (LALA) narrowband imaging survey Cetus field. We identify 110 of them as z~4.5 Ly{alpha} emitters based on single-line detections with no continuum emission blueward of the line. Six foreground galaxies are identified, either based on multiple lines or blueward continuum emission. The Ly{alpha} confirmation rate varies from <50% to 76% for candidates selected in different narrowband filters at slightly different redshifts. The sample includes many objects with equivalent widths (EWs)>~200{AA}. These large EW candidates are spectroscopically confirmed at the same rate as candidates with more modest EWs.2009ApJ...706..762Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/706/762CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/704/548 : Photometric properties of galaxies at z=4-6 (Overzier+, 2009)J/ApJ/696/546 : Ly{alpha} emitters at z~4.86 (Shioya+, 2009)J/ApJ/671/1227 : Ly{alpha} galaxies at z~4.5 (Dawson+, 2007)J/A+A/461/823 : Candidate Ly{alpha} emitting galaxies (Venemans+, 2007)J/ApJ/669/765 : Chandra X-ray sources in LALA Cetus field (Wang+, 2007)J/PASJ/57/881 : Imaging of high-redshift Lyman alpha emitters (Yamada+, 2005)J/AJ/127/213 : LALA Bootes field X-ray source catalog (Wang+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/706/762https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/706/762http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/706/762https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/706/762https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/706/762http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/706/762GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/706/762/table3 (IMACS spectroscopically confirmed Ly{alpha} emitters at z~4.5 in the LALA Cetus field)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/706/762/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/706/762/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/706/762/table3?GETtext/xml+votable180.050000true31.59625-4.8141670.0055555555555555566/17699 17702 17708https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/706/762?format=asciiOpticaldefaultJ/ApJ/706/762/table3IMACS spectroscopically confirmed Ly{alpha} emitters at z~4.5 in the LALA Cetus fieldl_EWLimit flag on EWmeta.code.error;spect.line.eqWidthcharrecnoRecord number assigned by the VizieR team.
