Carrying out deep follow-up spectroscopy of three candidates out of them using Subaru\/FOCAS and Keck\/DEIMOS, we identified one of them as a real z=7.215 LAE, and another as a tentative z=7.288 LAE.<br \/>\nIn the colloquium, I will demonstrate how to constrain the neutral fraction at z=7.3 using this LAE.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u3010\u65e5\u6642\u301110\u67085\u65e5(\u6c34)\u300010:30\uff5e12:00 \u3010\u5834\u6240\u3011\u56fd\u7acb\u5929\u6587\u53f0\u30fb\u4e09\u9df9\u3000\u4e2d\u592e\u68df\uff08\u5317\uff091\u968e \u8b1b\u7fa9\u5ba4 \u3010\u767a\u8868\u8005\uff08\u656c\u79f0\u7565\uff09\u3011\u6f81\u8c37\u3000\u9686\u4fca\uff08\u7dcf\u7814\u5927 D2\u30fb\u4e09\u9df9\u3001\u6307\u5c0e\u6559\u54e1 : \u5bb6 \u6b63\u5247 &#038; \u67cf\u5ddd \u4f38\u6210\uff09 \u3010\u30bf\u30a4\u30c8\u30eb\u3011T [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6,5],"tags":[],"class_list":["post-98","post","type-post","status-publish","format-standard","hentry","category-6","category-5"],"_links":{"self":[{"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=\/wp\/v2\/posts\/98","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=98"}],"version-history":[{"count":0,"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=\/wp\/v2\/posts\/98\/revisions"}],"wp:attachment":[{"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=98"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=98"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=98"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
