It is suggested that dust-to-stellar mass ratio can be used to probe evolutionary states of star-forming galaxies. In this talk I introduce the SED analysis of 162 dusty star-forming galaxies (DSFGs) selected by 1.1 mm ALMA observations. Using the latest modelling and fitting techniques to analyze the multiwavelength dataset, I derive the dust mass together with other physical properties. The negative correlation between M_dust\/M_star and age in post-starburst galaxies is also present in massive galaxies that are still actively forming stars. The distance above the star-forming main sequence decreases with increasing age. Such results may reflect a smooth evolution of DSFGs\u2019 physical properties.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dust-to-stellar mass ratio in 162 dusty star-forming galaxies speaker: Shuo Huang Abstract: Dust absorbs radia &hellip; <a href=\"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/2021-06-16-2\/\" class=\"more-link\"><span class=\"screen-reader-text\">&#8220;2021-06-16&#8221; \u306e<\/span>\u7d9a\u304d\u3092\u8aad\u3080<\/a><\/p>\n","protected":false},"author":17,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-1231","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/pages\/1231","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/users\/17"}],"replies":[{"embeddable":true,"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/comments?post=1231"}],"version-history":[{"count":1,"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/pages\/1231\/revisions"}],"predecessor-version":[{"id":1232,"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/pages\/1231\/revisions\/1232"}],"wp:attachment":[{"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/media?parent=1231"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
