I will then present some actual examples of narrow-band selected galaxies (H\u03b1, [OIII], [OII] emitters) and Balmer break galaxies at 0.4<z<1.5. I will discuss some science cases based on these unique statistical samples, and report some on-going analyses.\n\n[Speaker 2]\nSatoshi Kikuta, M2, SOKENDAI (supervisor :Masatoshi Imanishi)\n[Title]\nAGN feedback to neighbouring galaxy formation \n[Abstract]\nWhile feedback from active galactic nuclei (AGNs) is now considered to be an essential ingredient of the process of galaxy formation, the importance of AGN feedback to surrounding other galaxies is observationally unclear, although theoretically often expected to be at work especially to low-mass ones by heating the gas. To test whether QSO\u2019s radiative feedback is indeed strong enough to suppress the formation of neighboring low-mass galaxies, we have conducted a deep and wide field imaging observation with the Suprime-Cam on the Subaru telescope and searched for Lyman alpha emitters (LAEs) around QSOs at z~4.86 by using a narrow band filter. We compared the shape of luminosity functions of LAEs in the proximity of QSOs (the zone strongly affected by QSO\u2019s UV radiation) and in the blank fields where the influence of QSO radiation is negligible to find no clear difference even in the faintest luminosity bin where the feedback effect is expected to become the strongest. Our results suggests that i) the QSO radiative feedback does not affect LAE formation because LAEs have already formed before QSOs turned on and\/or duration of the QSO phase is too short, ii) we have to go deeper to witness feedback at work, or iii) the size of the QSO proximity is too large or too small compared to S-Cam FoV. We\u2019ll also provide future prospects of this study using the Hyper Suprime-Cam.  \n<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[Speaker 1] Rhythm Shimakawa, D3, SOKENDAI (supervisor : Tadayuki Kodama) [Title] Science cases based on narro [&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-585","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\/585","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=585"}],"version-history":[{"count":0,"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=\/wp\/v2\/posts\/585\/revisions"}],"wp:attachment":[{"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=585"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=585"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=585"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
