Thanks to our past narrow-band imaging survey (Mahalo-Subaru), we have a large sample of H\u03b1-selected star-forming galaxies. By combining them with MIPS 24um data, we probed ~50 dusty galaxies with IR luminosities above 5E11 Lsun. Since those also have spatially-resolved rest-UV image taken by Hubble Space Telescope, we can study morphological dependence of dust properties (IRX=IR\/UV). Our preliminary results show that for a given UV slope, \u201cUV-saturated\u201d galaxies have more heavily-obscured UV structures, which directly indicates that dust covering fraction increase rapidly than intrinsic UV luminosity as suggested by Reddy et al. 2010. Moreover, such highly-obscured galaxies tend to have high equivalent widths of H\u03b1 emission, which is also good agreement with dust properties of massive galaxies at low redshift (Koyama et al. 2015). <\/p>\n<p>[Speaker 2]<br \/>\n Masafusa Onoue, D1, SOKENDAI, Mitaka(supervisor: Nobunari Kashikawa)<br \/>\n [Title]<br \/>\n Addressing the Evolution of Super-massive Blackholes with Hyper Suprime-Cam Survey <\/p>\n","protected":false},"excerpt":{"rendered":"<p>[Speaker 1] Rhythm Shimakawa , D2, SOKENDAI, Mitaka(supervisor: Tadayuki Kodama) [Title] Rapid dust production [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6,5],"tags":[],"class_list":["post-420","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\/420","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=420"}],"version-history":[{"count":0,"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=\/wp\/v2\/posts\/420\/revisions"}],"wp:attachment":[{"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=420"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=420"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=420"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
