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_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": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "American Physical Society"}]}, "item_10_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://dx.doi.org/10.1103/PhysRevD.78.123534", "subitem_relation_type_select": "DOI"}}]}, "item_10_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "American Physical Society, All rights reserved."}]}, "item_10_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "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": "ISSN"}]}, "item_10_text_14": {"attribute_name": "\u30d5\u30a9\u30fc\u30de\u30c3\u30c8", "attribute_value_mlt": [{"subitem_text_value": "application/pdf"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Taruya, Atsushi"}], "nameIdentifiers": [{"nameIdentifier": "27402", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Koyama, Kazuya"}], "nameIdentifiers": [{"nameIdentifier": "27403", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Matsubara, Takahiko"}], "nameIdentifiers": [{"nameIdentifier": "27404", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-02-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "PhysRevD_78_123534.pdf", "filesize": [{"value": "602.9 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 602900.0, "url": {"label": "PhysRevD_78_123534.pdf", "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": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "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": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Signature of primordial non-Gaussianity on the matter power spectrum"}]}, "item_type_id": "10", "owner": "1", "path": ["336/695/696"], "permalink_uri": "http://hdl.handle.net/2237/11326", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2009-03-16"}, "publish_date": "2009-03-16", "publish_status": "0", "recid": "9533", "relation": {}, "relation_version_is_last": true, "title": ["Signature of primordial non-Gaussianity on the matter power spectrum"], "weko_shared_id": 3}
