A wide area (0fdg8 × 0fdg8) was mapped with high spatial resolution (17''). The line of sight samples the gas in both the Sagittarius arm and the interarm regions. The present observations reveal how the structure and physical conditions vary across a spiral arm. We classify the molecular gas in the line of sight into two distinct components based on its appearance: the bright and compact B component and the fainter and diffuse (i.e., more extended) D component. The B component is predominantly seen at the spiral arm velocities, while the D component dominates at the interarm velocities and is also found at the spiral arm velocities. We introduce the brightness distribution function and the brightness distribution index (BDI, which indicates the dominance of the B component) in order to quantify the map's appearance. The radial velocities of BDI peaks coincide with those of high 12CO J = 3-2/12CO J = 1-0 intensity ratio (i.e., warm gas) and H II regions, and tend to be offset from the line brightness peaks at lower velocities (i.e., presumably downstream side of the arm). Our observations reveal that the gas structure at small scales changes across a spiral arm: bright and spatially confined structures develop in a spiral arm, leading to star formation at the downstream side, while extended emission dominates in the interarm region.","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":"IOP Publishing/American Astronomical Society","subitem_publisher_language":"en"}]},"item_6_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1088/0004-637X/752/2/118","subitem_relation_type_select":"DOI"}}]},"item_6_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"American Astronomical Society","subitem_rights_language":"en"}]},"item_6_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0004637X","subitem_source_identifier_type":"PISSN"}]},"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":"Sawada, Tsuyoshi","creatorNameLang":"en"},{"creatorName":"サワダ, ツヨシ","creatorNameLang":"ja-Kana"},{"creatorName":"澤田, 剛士","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hasegawa, Tetsuo","creatorNameLang":"en"},{"creatorName":"ハセガワ, テツオ","creatorNameLang":"ja-Kana"},{"creatorName":"長谷川, 哲夫","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sugimoto, Masahiro","creatorNameLang":"en"},{"creatorName":"スギモト, マサヒロ","creatorNameLang":"ja-Kana"},{"creatorName":"杉本, 正宏","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Koda, Jin","creatorNameLang":"en"},{"creatorName":"コウダ, ジン","creatorNameLang":"ja-Kana"},{"creatorName":"幸田, 仁","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Handa, Toshihiro","creatorNameLang":"en"}],"familyNames":[{}],"givenNames":[{}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-27"}],"displaytype":"detail","filename":"HANDA_0004-637X_752_2_118.pdf","filesize":[{"value":"6.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"HANDA_0004-637X_752_2_118.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/1005/files/HANDA_0004-637X_752_2_118.pdf"},"version_id":"dcc5db76-392d-407a-858e-77a5b80d9f36"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Galaxy: disk","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ISM: clouds","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ISM: molecules","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"radio lines: ISM","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"surveys","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":"Structural Variation of Molecular Gas in the Sagittarius Arm and Interarm Regions","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Structural Variation of Molecular Gas in the Sagittarius Arm and Interarm Regions","subitem_title_language":"en"}]},"item_type_id":"6","owner":"18","path":["92"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2014-12-22"},"publish_date":"2014-12-22","publish_status":"0","recid":"1005","relation_version_is_last":true,"title":["Structural Variation of Molecular Gas in the Sagittarius Arm and Interarm Regions"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-02-07T07:01:09.776228+00:00"}
