The mapping area covers a 0.°5 x ×  0.°5 area involving several named molecular clouds, for example GCM -0.02-0.07, GCM -0.13-0.08, GCM 0.11-0.11, the Sickle molecular cloud, the Arched filaments molecular cloud, and so on. The data have an effective angular resolution of 26\"\". The H13CO+ emission line is a famous tracer of molecular gas mass because the line is optically thin, even in the Galactic center region, and is not emphasized by shock. The emission line presents a clumpy distribution of the molecular cloud. The averaged fractional abundance in the Sgr A complex is N (H13 CO+) /NH2 (1.8±0.4) ×10-11, comparing the LTE mass and the virial theorem mass. The SiO emission line is a famous and reliable tracer of shocked molecular gas. We find many molecular clouds that are remarkable only in the SiO emission line. Such molecular clouds have a large velocity width of up to 60km s-1. The brightness temperature ratio is up to TB(SiO)/  TB(H13CO+) < 8. The features are dominated by shock SiO-enriched gas. In such clouds, the ratio of the fractional abundance of SiO and  H13CO+ molecules is X (Si0)/ x(H13CO+)~ 100. The features are presumably made by supernova remnants. We found a prototypical example in GCM -0.02-0.07. It has two distinct structures. One is a ridge-like structure contacting with the Sgr A East shell; another is an expanding shell-like structure. There is a wide-velocity width ridge of SiO-enriched gas in GCM 0.11-0.11, which is adja-cent to Vertical filaments. This suggests that the collision with the molecular cloud accelerates relativistic electrons, which illuminate the Vertical filaments-Polarized Plumes complex.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_6_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"Astronomical Society of Japan","subitem_publisher_language":"en"},{"subitem_publisher":"日本天文学会","subitem_publisher_language":"ja"}]},"item_6_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1093/pasj/63.4.763","subitem_relation_type_select":"DOI"}}]},"item_6_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Astronomical Society of Japan","subitem_rights_language":"en"}]},"item_6_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00046264","subitem_source_identifier_type":"PISSN"}]},"item_6_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA1082896X","subitem_source_identifier_type":"NCID"}]},"item_6_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"440","subitem_subject_scheme":"NDC"}]},"item_6_version_type_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Tsuboi, Masato","creatorNameLang":"en"},{"creatorName":"坪井, 昌人","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tadaki, Ken-Ichi","creatorNameLang":"en"},{"creatorName":"但木, 謙一","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Miyazaki, Atsushi","creatorNameLang":"en"},{"creatorName":"宮崎, 敦","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Handa, Toshihiro","creatorNameLang":"en"},{"creatorName":"半田, 利弘","creatorNameLang":"ja"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-28"}],"displaytype":"detail","filename":"HANDA_0004-6264_63_763-794.pdf","filesize":[{"value":"12.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"HANDA_0004-6264_63_763-794.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/8605/files/HANDA_0004-6264_63_763-794.pdf"},"version_id":"50483763-ef9f-445d-9af0-d25eca3f0591"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Galaxy: center","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ISM: clouds","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ISM: magnetic fileds","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ISM: supernova remnants","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Sagittarius A Molecular Cloud Complex in H13CO+ and Thermal SiO Emission Lines","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Sagittarius A Molecular Cloud Complex in H13CO+ and Thermal SiO Emission Lines","subitem_title_language":"en"}]},"item_type_id":"6","owner":"18","path":["92"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2013-07-31"},"publish_date":"2013-07-31","publish_status":"0","recid":"8605","relation_version_is_last":true,"title":["Sagittarius A Molecular Cloud Complex in H13CO+ and Thermal SiO Emission Lines"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-02-07T07:18:45.048565+00:00"}
