As gravitational clustering develops, the coupling between different Fourier modes of density perturbations becomes important and the primordial non-Gaussianity which intrinsically possesses a nontrivial mode correlation can affect the late-time evolution of the power spectrum. We quantitatively estimate the non-Gaussian effect on the power spectrum from the perturbation theory. The potential impact on the cosmological parameter estimation using the power spectrum are investigated based on the Fisher-matrix formalism. In addition, on the basis of the local biasing prescription, non-Gaussian effects on the galaxy power spectrum are considered, showing that the scale-dependent biasing arises from a local-type primordial non-Gaussianity. On the other hand, an equilateral-type non-Gaussianity does not induce such scale dependence because of weaker mode correlations between small and large Fourier modes.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/11326"}]},"item_10_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Physical Society","subitem_publisher_language":"en"}]},"item_10_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1103/PhysRevD.78.123534","subitem_relation_type_select":"DOI"}}]},"item_10_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"American Physical Society, All rights reserved.","subitem_rights_language":"en"}]},"item_10_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_10_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1550-7998","subitem_source_identifier_type":"PISSN"}]},"item_10_text_14":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_text_value":"application/pdf"}]},"item_1615787544753":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Taruya, Atsushi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"27402","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koyama, Kazuya","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"27403","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsubara, Takahiko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"27404","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-02-20"}],"displaytype":"detail","filename":"PhysRevD_78_123534.pdf","filesize":[{"value":"602.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"PhysRevD_78_123534.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/9533/files/PhysRevD_78_123534.pdf"},"version_id":"2a46a84d-e7e7-4e2e-ad22-16c64b7e7766"}]},"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":"Signature of primordial non-Gaussianity on the matter power spectrum","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Signature of primordial non-Gaussianity on the matter power spectrum","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["696"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-03-16"},"publish_date":"2009-03-16","publish_status":"0","recid":"9533","relation_version_is_last":true,"title":["Signature of primordial non-Gaussianity on the matter power spectrum"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-16T03:55:14.393781+00:00"}
