Such leap forward in observational capabilities, already started with the launch of the James Webb Space Telescope, demands a comparable transformation in modeling techniques, that are currently lagging behind in accuracy. I will present ongoing efforts to build a solid theoretical framework to study this last frontier in structure formation. I will highlight current challenges in theoretical modeling and present a way forward to overcome them, to build the next state of the art in simulations of the first billion years of the Universe. Finally, I will show how new observations are enabling us to study the galaxy-IGM interplay during the tail end of reionization and place constraints on both galaxy formation and cosmic reionization models.<br><br><\/p>\n","protected":false},"excerpt":{"rendered":"<p>First galaxies,\u00a0cosmic reionization and their interplay\u00a0\u2013\u00a0successes and challenges of numerical models Speaker &hellip; <a href=\"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/2025\/06\/18\/2025-06-25\/\" class=\"more-link\"><span class=\"screen-reader-text\">&#8220;2025-06-25&#8221; \u306e<\/span>\u7d9a\u304d\u3092\u8aad\u3080<\/a><\/p>\n","protected":false},"author":31,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-2543","post","type-post","status-publish","format-standard","hentry","category-1"],"_links":{"self":[{"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/posts\/2543","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/users\/31"}],"replies":[{"embeddable":true,"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/comments?post=2543"}],"version-history":[{"count":1,"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/posts\/2543\/revisions"}],"predecessor-version":[{"id":2544,"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/posts\/2543\/revisions\/2544"}],"wp:attachment":[{"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/media?parent=2543"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/categories?post=2543"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/tags?post=2543"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
