The XRT had observed over 290 X-ray afterglows of GRBs at the time of this meeting, obtaining > 80 % of the world total of GRB X-ray afterglows and > 70 % of the world total of GRBs with redshifts. I discuss general characteristics of X-ray afterglows as observed by Swift, and will then focus on a few of our most interesting discoveries. One of the most exciting of these was the recent \"naked-eye\" burst, GRB 080319B, with the brightest optical counterpart ever seen and one of the best-observed X-ray and optical light curves ever obtained. We interpret the bright prompt emission as the result of an extremely large bulk Lorentz factor, combined with a very narrow jet beamed directly at us, with Synchrotron Self-Compton emission from the UV/optical photons accounting for the gamma-ray emission. The X-ray and optical afterglows are interpreted as the result of a two-component jet, with the wide jet accounting for the optical afterglow, while the X-ray afterglow is initially dominated by the narrow jet until that component fades following its jet break.","subitem_description_type":"Other"}]},"item_5_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064306045","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_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Astronomy & Astrophysics, Pennsylvania State University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Burrows, David N.","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":"64306045.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"64306045.pdf","url":"https://jaxa.repo.nii.ac.jp/record/5284/files/64306045.pdf"},"version_id":"57001022-319c-4cca-8a28-167bea3e1504"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"missions : Swift - GRBs : X-ray afterglows - GRB 080319B","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":"Recent results of GRB X-ray afterglows","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Recent results of GRB X-ray afterglows","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["959","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"5284","relation_version_is_last":true,"title":["Recent results of GRB X-ray afterglows"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:18:43.170543+00:00"}
