Recently, Risaliti, Lusso & collaborators [1-3] have succeeded in producing a high redshift Hubble diagram (z less than or similar to 7) that supports \"a trend whereby the Hubble diagram of quasars is well reproduced by the standard flat Lambda CDM model up to z similar to 1.5 - 2, but strong deviations emerge at higher redshifts\". This conclusion hinges upon a log polynomial expansion for the luminosity distance. In this note, we demonstrate that this expansion (or \"improvements\" thereof) typically can only be trusted up to z similar to 1.5 - 2. As a result, a breakdown in the validity of the expansion may be misinterpreted as a (phantom) deviation from flat Lambda CDM. We further illustrate the problem through mock data examples.","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":" Elsevier B.V."}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1016/j.physletb.2021.136366","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_17":{"attribute_name":"Related site","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.sciencedirect.com/science/article/pii/S0370269321003063","subitem_relation_type_select":"URI"}}]},"item_10001_rights_15":{"attribute_name":"Rights","attribute_value_mlt":[{"subitem_rights":"© 2021 The Author(s)"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0370-2693","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"attribute_name":"Author's flag","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-09-08"}],"displaytype":"detail","filename":"Banerjee-2021-On-problems-with-cosmography-in-.pdf","filesize":[{"value":"486.7 kB"}],"format":"application/pdf","license_note":"CC BY 4.0\nCreative Commons Attribution 4.0 International (https://creativecommons.org/licenses/by/4.0/)","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Banerjee-2021-On-problems-with-cosmography-in-","url":"https://oist.repo.nii.ac.jp/record/2248/files/Banerjee-2021-On-problems-with-cosmography-in-.pdf"},"version_id":"9e78fce1-0fd4-47a7-8395-d02988567e68"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"COSMOLOGICAL CONSTRAINTS","subitem_subject_scheme":"Other"},{"subitem_subject":"HUBBLE DIAGRAM","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":"On problems with cosmography in cosmic dark ages","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"On problems with cosmography in cosmic dark ages","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"31","path":["170"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-09-08"},"publish_date":"2021-09-08","publish_status":"0","recid":"2248","relation_version_is_last":true,"title":["On problems with cosmography in cosmic dark ages"],"weko_creator_id":"31","weko_shared_id":31},"updated":"2023-06-26T11:34:18.186440+00:00"}
