With the high energy-resolution and the low background, particularly in the hard X-ray band of Suzaku, we obtained accurate fluxes of these lines. We constrain the GCDX region using the longitude and latitude distribution of the 6.7keV lines; The GCDX is extended +/- 0.42 deg and +/- 0.16 deg in the longitude and latitude e-folding scales from Sgr A(sup *). Neither the 6.4 keV nor 6.7 keV line flux shows close proportionality to the continuum flux (5-10 keV band); the 6.4 keV line shows excess in the high flux side, and vice versa for the 6.7 keV line. On the other hand, the sum of the 6.4 keV plus 6.7 keV line fluxes with the ratio of 1:2 shows good proportionality to the continuum flux, hence we phenomenologically decompose the continuum flux of the GCDX into the 6.4 keV- and 6.7 keV-associated continuums with the flux ratio of 1:2. The GC spectrum is also fit by a 6.5 keV-temperature plasma and a power-law continuum of the photon index 1.4 plus Gaussian lines at 6.4 keV and 7.05 keV. The fluxes of these two components are nearly the same with each others. Based on these facts, we estimate the flux ratio due to the diffuse and the integrated point sources as 6:1, consistent with that derived from the scale-height analysis of 7:1. We also determine the line-of-sight positions of the molecular clouds (MC) from the analysis of absorption and 6.4 keV flux relation of the GCDX spectra, and find that the MCs lie on the parabola with the focus at Sgr A(sup *). This is an equi-delay-time locus of about 300 light years for the X-ray originated from Sgr A(sup *) and reflected by the MC into our line of sight. The bright 6.4 keV clumps (MCs) of the Sgr B region exhibit time variability over about 10 years. Accordingly, we suspect that Sgr A(sup *) exhibited a large flare about 300 years ago with the variability time scale of about 10 years.","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: AA0064574051","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":"京都大学大学院理学研究科物理学専攻"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Physics, Graduate School of Science, Kyoto University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小山, 勝二"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Koyama, Katsuji","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":"64574051.pdf","filesize":[{"value":"271.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"64574051.pdf","url":"https://jaxa.repo.nii.ac.jp/record/4983/files/64574051.pdf"},"version_id":"71d0fa04-de9a-41c3-b6fb-5cb423fc3176"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Galaxy: center - ISM: supernova remnant - X-ray spectra","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":"The Suzaku Results of the Galactic Center Diffuse X-Ray Emission","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The Suzaku Results of the Galactic Center Diffuse X-Ray Emission","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":"4983","relation_version_is_last":true,"title":["The Suzaku Results of the Galactic Center Diffuse X-Ray Emission"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:27:01.330964+00:00"}
