cds-question@unistra.frgalaxiesvisible-astronomyultraviolet-astronomyinfrared-photometrybroad-band-photometryWe present results of a survey for Ly{alpha} emitters at z~4.86 based on optical narrowband ({lambda}c=7126{AA}, {Delta}{lambda}=73{AA}) and broadband (B, V, r', i', and z') observations of the Cosmic Evolution Survey field using Suprime-Cam on the Subaru Telescope. We find 79 Ly{alpha} emitter (LAE) candidates at z~4.86 over a contiguous survey area of 1.83deg^2^, down to the Ly{alpha} line flux of 1.47x10^-17^erg/s/cm^2^. We obtain the Ly{alpha} luminosity function with a best-fit Schechter parameters of log L*=42.9^+0.5^_-0.3_erg/s and {Phi}*=1.2^+8.0^_-1.1_x10^-4^Mpc^-3^ for {alpha}=-1.5 (fixed). The two-point correlation function for our LAE sample is {xi}(r)=(r/4.4^+5.7^_-2.9_Mpc)^-1.90+/-0.22^. In order to investigate the field-to-field variations of the properties of Ly{alpha} emitters, we divide the survey area into nine tiles of 0.5x0.5{deg} each. We find that the number density varies with a factor of ~2 from field to field with high statistical significance. However, we find no significant field-to-field variance when we divide the field into four tiles with 0.7x0.7{deg} each. We conclude that at least 0.5deg^2^ survey area is required to derive averaged properties of LAEs at z~5, and our survey field is wide enough to overcome the cosmic variance.2009ApJ...696..546Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/696/546CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/498/13 : Lyman-{alpha} emitters from redshifts z~2-3 (Nilsson+, 2009)J/ApJS/175/128 : H{alpha} emitting galaxies in COSMOS-2 field (Shioya+, 2008)J/ApJS/172/456 : [OII] emitting galaxies in COSMOS + SDF fields (Takahashi+,J/ApJS/172/523 : COSMOS field Ly{alpha} emitters at z~5.7 (Murayama+, 2007)J/PASJ/58/313 : Ly{alpha} emitters in the SUBARU Deep Field (Shimasaku+, 2006)J/ApJ/648/7 : Ly{alpha} emitters at z=6.5 in Subaru Deep Field (Kashikawa+,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/696/546https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/696/546http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/696/546https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/696/546https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/696/546http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/696/546GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/696/546/table1 (Photometric properties of Ly{alpha} emitter (LAE) candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/696/546/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/696/546/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/696/546/table1?GETtext/xml+votable180.050000true150.689831.59803890.0055555555555555565/6814 6/27245 27247 273442.7723443941582964e-19 2.8028570465771445e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/696/546?format=asciiUVOpticalInfrareddefaultJ/ApJ/696/546/table1Photometric properties of Ly{alpha} emitter (LAE) candidatesl_EW0Limit flag on EW0meta.code.errorcharrecnoRecord number assigned by the VizieR team.
