The emission mechanism of this new enigmatic component has not yet been conclusively unveiled. Last two years, Suzaku has performed two target-of-opportunity (ToO) observations: the first one pointing on the newly discovered magnetar SGR 0501+4516, and the second one on the radio transient magnetar 1E 1547.0-5408, both soon after a large X-ray outburst. Suzaku successfully detected extremely hard power-law components with gamma = 0.79 and 1.54 for SGR 0501+4516 and 1E 1547.0-5408, respectively, as well as their soft X-ray thermal and non-thermal emissions. We found that the hard X-ray fluxes are comparable to or larger than the soft X-rays, and the wide-band spectrum of SGR 0501+4516 looked more like AXPs, while 1E 1547.0-5408 has a spectrum more similar to SGRs. Furthermore, combining these results with published ones, we found that the ratio of hard over soft X-ray flux of magnetars, seems to negatively (or positively) correlate with their characteristic ages (or magnetic fields). This gives a further hint for unifying SGRs and AXPs into one scheme, directly connected to decay of the magnetic activity in the evolution of magnetars. Now a magnetar key project is in progress, where 10 magnetars have already been observed to emit hard X-rays.","subitem_description_type":"Other"}]},"item_5_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Meeting sponsors: The University of Tokyo, The Institute of Physical and Chemical Research, The Japan Society for the Promotion of Science","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064574066","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-09-008E","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"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学理学系研究科物理学専攻"},{"subitem_text_value":"理化学研究所"},{"subitem_text_value":"東京大学理学系研究科物理学専攻"},{"subitem_text_value":"東京大学理学系研究科物理学専攻"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Physics, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Institut de Ciencies de l'Espai (ICE-CSIC, IEEC)"},{"subitem_text_language":"en","subitem_text_value":"Cosmic Radiation Laboratory, Institute of Physical and Chemical Research (RIKEN)"},{"subitem_text_language":"en","subitem_text_value":"Department of Physics, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"NASA Goddard Space Flight Center"},{"subitem_text_language":"en","subitem_text_value":"Department of Physics, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Suzaku Magnetar team"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"榎戸, 輝揚"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中川, 友進"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中澤, 知洋"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"牧島, 一夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Enoto, Teruaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Rea, N.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakagawa, Yujin E.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakazawa, Kazuhiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sakamoto, T.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Makishima, Kazuo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Suzaku Magnetar team","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":"2020-01-16"}],"displaytype":"detail","filename":"64574066.pdf","filesize":[{"value":"558.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"64574066.pdf","url":"https://jaxa.repo.nii.ac.jp/record/4998/files/64574066.pdf"},"version_id":"cecbb6de-6a9f-4dca-9df3-55278e90ae33"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"individual (SGR 0501+4516; 1E 1547.0-5408; 4U 0142+61) - X-rays: stars","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"Suzaku Studies of the Extremely Hard Emission Components of Magnetars","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Suzaku Studies of the Extremely Hard Emission Components of Magnetars","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["948","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"4998","relation_version_is_last":true,"title":["Suzaku Studies of the Extremely Hard Emission Components of Magnetars"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-06-20T19:46:43.606850+00:00"}
