The observations were carried out with the FOCAS instrument on the Subaru Telescope and yielded an extremely high polarization sensitivity of delta(p) similar to 0.1%, at a resolving power of R similar to 1500. HS 1603+3820 has been the target of a high-resolution spectroscopic monitoring campaign for more than four years, aimed at studying its highly variable C VI mini-BAL profile. Using the monitoring observations in an earlier paper, we were able to narrow down the causes of the variability to the following two scenarios: (1) scattering material of variable optical depth redirecting photons around the absorber and (2) a variable, highly ionized screen between the continuum source and the absorber which modulates the UV continuum incident on the absorber. The observations presented here provide a crucial test of the scattering scenario and lead us to disfavor it because (1) the polarization level is very small (p similar to 0.6%) throughout the spectrum and (2) the polarization level does not increase across the mini-BAL trough. Thus, the variable screen scenario emerges as our favored explanation of the C VI mini-BAL variability. Our conclusion is bolstered by recent X-ray observations of nearby mini-BAL quasars, which show a rapidly variable soft X-ray continuum that appears to be the result of transmission through an ionized absorber of variable ionization parameter and optical depth.","subitem_description_type":"Abstract"}]},"item_6_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_6_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"The Astrophysical Journal. 719(2):1890-1895 (2010)","subitem_description_type":"Other"}]},"item_6_link_3":{"attribute_name":"信州大学研究者総覧へのリンク","attribute_value_mlt":[{"subitem_link_text":"Misawa, Toru","subitem_link_url":"http://soar-rd.shinshu-u.ac.jp/profile/ja.ypchuUkV.html"}]},"item_6_link_67":{"attribute_name":"WoS","attribute_value_mlt":[{"subitem_link_url":"http://gateway.isiknowledge.com/gateway/Gateway.cgi?&GWVersion=2&SrcAuth=ShinshuUniv&SrcApp=ShinshuUniv&DestLinkType=FullRecord&DestApp=WOS&KeyUT=000280658000068"}]},"item_6_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IOP PUBLISHING LTD"}]},"item_6_relation_48":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1088/0004-637X/719/2/1890"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1088/0004-637X/719/2/1890","subitem_relation_type_select":"DOI"}}]},"item_6_rights_62":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright (c) 2010 The American Astronomical Society"}]},"item_6_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0004-637X","subitem_source_identifier_type":"ISSN"}]},"item_6_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00553253","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Misawa,  Toru"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kawabata,  Koji S."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Eracleous,  Michael"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Charlton,  Jane C."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kashikawa,  Nobunari"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-28"}],"displaytype":"detail","filename":"SPECTROPOLARIMETRIC_TEST_STRUCTURE.pdf","filesize":[{"value":"581.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SPECTROPOLARIMETRIC_TEST_STRUCTURE.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/15869/files/SPECTROPOLARIMETRIC_TEST_STRUCTURE.pdf"},"version_id":"380bfe0b-e952-44ed-97ba-afadea0b9c73"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"quasars: absorption lines","subitem_subject_scheme":"Other"},{"subitem_subject":"quasars: individual (HS 1603+3820)","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":"A SPECTROPOLARIMETRIC TEST OF THE STRUCTURE OF THE INTRINSIC ABSORBERS IN THE QUASAR HS 1603+3820*","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A SPECTROPOLARIMETRIC TEST OF THE STRUCTURE OF THE INTRINSIC ABSORBERS IN THE QUASAR HS 1603+3820*","subitem_title_language":"en"}]},"item_type_id":"6","owner":"1","path":["1545"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-10-19"},"publish_date":"2010-10-19","publish_status":"0","recid":"15869","relation_version_is_last":true,"title":["A SPECTROPOLARIMETRIC TEST OF THE STRUCTURE OF THE INTRINSIC ABSORBERS IN THE QUASAR HS 1603+3820*"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-14T04:01:46.047691+00:00"}
