However, the contribution from z greater than 6 galaxies to cosmic reionization critically depends on the fraction of ionizing (Lyman continuum, LyC) photons escaping from these objects and into the intergalactic medium. At z less than or equal to 4, the escaping LyC flux can be measured directly, but the opacity of the neutral intergalactic medium precludes such measurements at higher redshifts. In a recent paper, we argue that since the LyC escape fraction regulates the contribution of nebular emission to the rest-frame optical/UV spectra of galaxies, the James Webb Space Telescope should be able to indirectly assess the LyC escape fraction for galaxies at z approx. 6-9. JWST can, on the other hand, not constrain the fraction of LyC photons directly absorbed by dust, and this is where SPICA comes in. The dust continuum emission from gravitationally lensed LyC-leakers at z approx. 6 may in principle be detectable with SPICA, thereby constraining the level of LyC extinction in these objects.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_5_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA1730027017","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-17-010E","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構(JAXA)"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_22":{"attribute_name":"ISSNONLINE","attribute_value_mlt":[{"subitem_source_identifier":"2433-2232","subitem_source_identifier_type":"ISSN"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Stockholm University"},{"subitem_text_value":"大阪産業大学"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Stockholm University"},{"subitem_text_language":"en","subitem_text_value":"Osaka Sangyo University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Zackrisson, Erik"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"井上, 昭雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Zackrisson, Erik","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Inoue, Akio K.","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-15"}],"displaytype":"detail","filename":"AA1730027017.pdf","filesize":[{"value":"498.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1730027017.pdf","url":"https://jaxa.repo.nii.ac.jp/record/2994/files/AA1730027017.pdf"},"version_id":"041d16f0-e778-43f2-8d1c-1aefece97c6f"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"SPICA as a Probe of Cosmic Reionization","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"SPICA as a Probe of Cosmic Reionization","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["807","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-05-01"},"publish_date":"2018-05-01","publish_status":"0","recid":"2994","relation_version_is_last":true,"title":["SPICA as a Probe of Cosmic Reionization"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:12:29.771045+00:00"}
