cds-question@unistra.frsurveysphotometryredshiftedline-intensitiesultraviolet-astronomyNarrow-band surveys to detect Ly{alpha} emitters are powerful tools for identifying high, and very high, redshift galaxies. Although samples are increasing at redshifts z=3-6, the nature of these galaxies is still poorly known. The number of galaxies detected at redshifts below z~3 are also small. We study the properties of z=2.25 Ly{alpha} emitters and compare them with those of z>3 Ly{alpha} emitters We present narrow-band imaging made with the MPG/ESO 2.2m telescope and the WFI (Wide Field Imager) detector. Using this data, we have searched for emission-line objects. We find 170 candidate typical Ly{alpha} emitters and 17 candidates that we regard as high UV-transmission Ly{alpha} emitters. We have derived the magnitudes of these objects in 8 photometric bands from u* to K_s_, and studied whether they have X-ray and/or radio counterparts.2009A&A...498...13Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/498/13CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/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/A+A/498/13https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/498/13http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/498/13https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/498/13https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/498/13http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/498/13GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/498/13/table2 (Coordinates, observed equivalent widths, continuum subtracted narrow-band magnitudes and UV spectral index {beta} of the likely candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/498/13/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/498/13/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/498/13/table2?GETtext/xml+votable180.050000true150.05311.947970.0055555555555555566/27256 27258https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/498/13?format=asciiUVOpticaldefaultJ/A+A/498/13/table2Coordinates, observed equivalent widths, continuum subtracted narrow-band magnitudes and UV spectral index {beta} of the likely candidatesrecnoRecord number assigned by the VizieR team.
