cds-question@unistra.frsurveysphotometryredshiftedline-intensitiesWe present new results of a deep optical imaging survey using a narrow band filter (NB921) centered at {lambda}=9196{AA} together with B, V, R, i', and z' broadband filters in the sky area of the Subaru Deep Field, which has been promoted as one of legacy programs of the 8.2m Subaru Telescope. We obtained a photometric sample of 58 Ly{alpha} emitter candidates at z~6.5-6.6 among ~180 strong NB921-excess (z'-NB921>1.0) objects together with a color criterion of i'-z'>1.3. We then obtained optical spectra of 20 objects in our NB921-excess sample, and identified at least nine Ly{alpha} emitters at z~6.5-6.6, including the two emitters reported by Kodaira et al. (2003PASJ...55L..17K). Since our Ly{alpha}-emitter candidates are free from strong amplification of gravitational lensing, we are able to discuss their observational properties from a statistical point of view. Based on these new results, we obtained a lower limit of the star-formation rate density of rho_SFR_~5.7x10^-4^h_0.7_M_{sun}/yr/Mpc^3^ at z~6.6, being consistent with our previous estimate. We discuss the nature of star-formation activity in galaxies beyond z=6.2005PASJ...57..165Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PASJ/57/165CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/PASJ/57/881 : Imaging of high-redshift Lyman alpha emitters (Yamada+, 2005)J/A+A/431/793 : Ly-alpha emitters around MRC 0316-257 (Venemans+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PASJ/57/165https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PASJ/57/165http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PASJ/57/165https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PASJ/57/165https://vizier.iucaa.in/viz-bin/votable?-source=J/PASJ/57/165http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PASJ/57/165GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PASJ/57/165/table2 (Photometric properties of the Ly{alpha} emitters (LAEs).
