In fact, with AKARI, we find that the ratio of the PAH 3.3 μm to IR luminosity, L(sub PAH3.3)/L(sub IR), considerably decreases toward the luminous end of L(sub IR) greater than 10(exp11.5) solar liminosity, using the near-IR (2.5-5 μm) spectra of 100 IR galaxies without AGN signatures. We conclude that local ULIRGs intrinsically possess a smaller amount of PAHs relative to classical grains than less-luminous IR galaxies. Some fraction of PAHs may have been destroyed once by a shock during a merging process, whereas large dust grains survive, which may explain the systematically low abundance ratios of PAHs to classical grains observed for the ULIRGs. To prove this scenario, we should observe a systematic change of the ratio from an interacted region to others, or from outer to inner areas, within a galaxy. With SPICA, especially coronagraphic spectroscopy with the SCI, we can perform a spatially-resolved study of local ULIRGs in both PAH and dust emission, which will reveal the scene of the processing and destruction of dust grains with shocks during merging processes of galaxies.","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: AA1730027027","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":"名古屋大学"},{"subitem_text_value":"名古屋大学"},{"subitem_text_value":"名古屋大学"},{"subitem_text_value":"名古屋大学"},{"subitem_text_value":"名古屋大学"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Nagoya University"},{"subitem_text_language":"en","subitem_text_value":"Nagoya University"},{"subitem_text_language":"en","subitem_text_value":"Nagoya University"},{"subitem_text_language":"en","subitem_text_value":"Nagoya University"},{"subitem_text_language":"en","subitem_text_value":"Nagoya University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山田, 梨加"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"金田, 英宏"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大薮, 進喜"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山岸, 光義"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"石原, 大助"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamada, Rika","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kaneda, Hidehiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Oyabu, Shinki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamagishi, Mitsuyoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ishihara, Daisuke","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":"AA1730027027.pdf","filesize":[{"value":"274.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1730027027.pdf","url":"https://jaxa.repo.nii.ac.jp/record/3004/files/AA1730027027.pdf"},"version_id":"f3b5bb81-3340-4961-8c3b-34bdbb9586a9"}]},"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":"A Spatially-resolved Study on the Processing and Destruction of Dust Grains in Local ULIRGs","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A Spatially-resolved Study on the Processing and Destruction of Dust Grains in Local ULIRGs","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":"3004","relation_version_is_last":true,"title":["A Spatially-resolved Study on the Processing and Destruction of Dust Grains in Local ULIRGs"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:12:14.476128+00:00"}
