The near-infrared flux variations are almost synchronized with the flux variation in the V band. This indicates that the intraday-variable component of near-infrared continuum emission of the NGC 4395 nucleus is an extension of UV-optical power-law continuum emission and originates in an outer region of the central accretion disk. In addition, a possible time lag of ca. 7 minutes between the V-band and infrared flux variations was found by cross-correlation analysis. These results can be explained by the X-ray reprocessing model, in which X-ray flux variation propagates with light velocity and drives the flux variations in optical and near-infrared wavelengths. We also carried out the most intense monitoring observations in the optical and near-infrared wavebands for a Seyfert 1 galaxy, NGC 5548, and examined the correlation between the X-ray and optical flux variations. The X-ray light curve was taken from Uttley et al. (2003) as observed by the Rossi X-ray Timing Explorer (RXTE). The V-band flux variation shows a clear lag of 1 - 2 days behind the X-ray flux variation, which supports the X-ray reprocessing model for the optical flux variation at short timescales.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"著者人数: 11人","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064306043","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-08-014E","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天文学教育研究センター"},{"subitem_text_value":"東京大学理学系研究科天文学教育研究センター"},{"subitem_text_value":"国立天文台"},{"subitem_text_value":"宇宙航空研究開発機構宇宙科学研究本部"},{"subitem_text_value":"国立天文台"},{"subitem_text_value":"東京大学理学系研究科天文学教育研究センター"},{"subitem_text_value":"東京大学理学系研究科天文学専攻"},{"subitem_text_value":"東京大学理学系研究科天文学専攻"},{"subitem_text_value":"東京大学理学系研究科天文学専攻"},{"subitem_text_value":"東京大学理学系研究科天文学専攻"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Astronomy, School of Science, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Institute of Astronomy, School of Science, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"National Astronomical Observatory"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (ISAS)(JAXA)"},{"subitem_text_language":"en","subitem_text_value":"National Astronomical Observatory"},{"subitem_text_language":"en","subitem_text_value":"Institute of Astronomy, School of Science, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Department of Astronomy, School of Science, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Department of Astronomy, School of Science, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Department of Astronomy, School of Science, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Department of Astronomy, School of Science, University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"峰崎, 岳夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"吉井, 讓"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小林, 行泰"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"塩谷, 圭吾"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"菅沼, 正洋"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Minezaki, Takeo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yoshii, Yuzuru","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kobayashi, Yukiyasu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Enya, Keigo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Suganuma, Masahiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tomita, Hiroyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Koshida, Shintaro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamauchi, Masahiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sakata, Yu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sugawara, Shota","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":"64306043.pdf","filesize":[{"value":"323.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"64306043.pdf","url":"https://jaxa.repo.nii.ac.jp/record/5282/files/64306043.pdf"},"version_id":"2afa101e-8999-42b0-b421-131e83a08c86"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"AGN : time variation -
