We found that: 1) The observed data are consistent with the cold dark matter (CDM) based cosmological model. 2) The observed data are not consistent with the warm dark matter (WDM) model if the WDM mass is smaller than 1/400 of the electron mass. These results imply that the origin of primordial minihalos, which are considered to be the progenitors of primordial galaxies is CDM rather tan WDM. On the other hand, we found that observational data of the Milky Way and the Andromeda galaxies suggest that some associated dwarf galaxies have a core rather than a cusp. This relult is not consistent with the CDM prediction.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基盤研究(B);  研究期間：2013～2015;   課題番号：25287062;   研究分野：宇宙論;   科研費の分科・細目：","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_relation_11":{"attribute_name":"著者 外部リンク","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-25287062/"}]}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"},{"subitem_text_value":"研究分担者"},{"subitem_text_value":"研究分担者"},{"subitem_text_value":"研究分担者"},{"subitem_text_value":"研究協力者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"INOUE, Kaiki"},{"subitem_text_language":"en","subitem_text_value":"CHIBA Masashi"},{"subitem_text_language":"en","subitem_text_value":"MINEZAKI Takeo"},{"subitem_text_language":"en","subitem_text_value":"TAKAHASHI Ryuichi"},{"subitem_text_language":"en","subitem_text_value":"MATSUSHITA Satoki"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学理工学部; 准教授"},{"subitem_text_value":"東北大学大学院理学研究科; 教授"},{"subitem_text_value":"東京大学大学院理学研究科; 助教"},{"subitem_text_value":"弘前大学理工学研究科; 助教"},{"subitem_text_value":"中央研究院天文及天文物理研究所; 副研究員"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kindai University"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"井上, 開輝"},{"creatorName":"イノウエ, カイキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"千葉, 柾司"},{"creatorName":"チバ, マサシ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"峰崎, 岳夫"},{"creatorName":"ミネザキ, タケオ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"高橋, 龍一"},{"creatorName":"タカハシ, リュウイチ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"松下, 聡樹"},{"creatorName":"マツシタ, サトシ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-17"}],"displaytype":"detail","filename":"25287062seika.pdf","filesize":[{"value":"90.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"25287062seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/18045/files/25287062seika.pdf"},"version_id":"03277f9c-1b4e-4e8d-94c5-f51870b52f50"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ダークマター","subitem_subject_scheme":"Other"},{"subitem_subject":"重力レンズ","subitem_subject_scheme":"Other"},{"subitem_subject":"宇宙論","subitem_subject_scheme":"Other"},{"subitem_subject":"銀河形成","subitem_subject_scheme":"Other"},{"subitem_subject":"サブハロー","subitem_subject_scheme":"Other"},{"subitem_subject":"サブミリ波","subitem_subject_scheme":"Other"},{"subitem_subject":"フラックス比異常","subitem_subject_scheme":"Other"},{"subitem_subject":"矮小銀河","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"重力レンズ現象から探る始原ミニハローの起源","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"重力レンズ現象から探る始原ミニハローの起源"},{"subitem_title":"Probing the origin of primordial minihalos with gravitational lensing","subitem_title_language":"en"}]},"item_type_id":"8","owner":"29","path":["4296"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-10-17"},"publish_date":"2016-10-17","publish_status":"0","recid":"18045","relation_version_is_last":true,"title":["重力レンズ現象から探る始原ミニハローの起源"],"weko_creator_id":"29","weko_shared_id":-1},"updated":"2023-06-20T22:10:35.728776+00:00"}
