This effect is eminent in the direction of the Galactic Center. To measure the distance to the Galactic Center with the relative error of a few percent, in addition to the astrometric microlensing by individual stars in the Galaxy, the macro lens effect, the collective gravitational deflection by the core and the bulge of the Galaxy must be considered. This effect is important because it has a secular component. Its magnitude is 0.4 micro-as/yr in the case of internal motion of QSOs by the core and reaches 0.6 micro-as/yr in the case of the collective motion produced by both the core and the bulge. The measurement of these effects will provide valuable information on the density and mass function of the Galactic Center.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0048096002","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宇宙科学研究本部"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"長野工業高等専門学校"},{"subitem_text_value":"情報通信研究機構"},{"subitem_text_value":"国立天文台"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Nagano National College of Technology"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Information and Communications Technology"},{"subitem_text_language":"en","subitem_text_value":"National Astronomical Observatory"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"大西, 浩次"}],"nameIdentifiers":[{"nameIdentifier":"432785","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"細川, 瑞彦"}],"nameIdentifiers":[{"nameIdentifier":"432786","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"福島, 登志夫"}],"nameIdentifiers":[{"nameIdentifier":"432787","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Onishi, Koji","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"432788","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hosokawa, Mizuhiko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"432789","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fukushima, Toshio","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"432790","nameIdentifierScheme":"WEKO"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"星雲中心","subitem_subject_scheme":"Other"},{"subitem_subject":"重力偏向","subitem_subject_scheme":"Other"},{"subitem_subject":"QSO","subitem_subject_scheme":"Other"},{"subitem_subject":"レンズ","subitem_subject_scheme":"Other"},{"subitem_subject":"恒星","subitem_subject_scheme":"Other"},{"subitem_subject":"密度","subitem_subject_scheme":"Other"},{"subitem_subject":"モデル","subitem_subject_scheme":"Other"},{"subitem_subject":"クェーサー","subitem_subject_scheme":"Other"},{"subitem_subject":"galactic center","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"gravitational deflection","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"QSO","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"lens","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"star","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"density","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"model","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"quasar","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":"MACRO lens toward the Galactic Center: Secular component of apparent proper motion of QSOs induced by gravitational lens of the galaxy","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"MACRO lens toward the Galactic Center: Secular component of apparent proper motion of QSOs induced by gravitational lens of the galaxy","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"38319","relation_version_is_last":true,"title":["MACRO lens toward the Galactic Center: Secular component of apparent proper motion of QSOs induced by gravitational lens of the galaxy"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T22:42:18.221789+00:00"}
